When drag racing john timed yourself 40 meters per second seven seconds after starting what was your acceleration during this time?

What is the average acceleration during the time interval 0 seconds to 10 seconds?

The average acceleration during the time interval from 0 to 10 seconds is the change in velocity divided by the time interval. If you provide the initial and final velocities during this time interval, we can calculate the average acceleration for you.

How do you calculate acceleration between 6 and 9 seconds?

To calculate acceleration between 6 and 9 seconds, you need to find the change in velocity during that time interval and then divide it by the time taken. The formula for acceleration is acceleration = (final velocity - initial velocity) / time. Plug in the velocities at 6 seconds and 9 seconds into the formula to get the acceleration.

What is the equation used to calculate the accerleration of an object?

Change of speed divided by time gives you average acceleration. For example, a change of 30 m/s during 5 seconds gives you 6 meters per second square - this is the average acceleration during those 5 seconds. If acceleration is constant, then this is also the acceleration at any moment during those 5 seconds. For more complicated functions (non-constant acceleration), derivates (a topic in calculus) has to be used. Specifically, the acceleration is the derivative of the velocity.

What is an example of average acceleration?

An example of average acceleration would be a car starting from a stop and gradually increasing its speed to 60 mph over a period of 10 seconds. The average acceleration of the car during this time would be calculated as the change in velocity divided by the time taken to achieve that change.

The magnitude of the acceleration of the during the first 3 seconds is?

The magnitude of acceleration during the first 3 seconds can be determined by calculating the change in velocity over that time period. By dividing this change in velocity by the time interval (3 seconds), you can find the average acceleration magnitude during that time.

A rave car starts from rest and accelerates uniformly to a speed of 40 ms in 8.0 seconds. How far will the car travel during the 8 seconds?

The distance the car travels during the acceleration can be calculated using the formula: distance = (initial velocity)(time) + 0.5(acceleration)(time)^2. Plug in the values: initial velocity = 0 m/s, final velocity = 40 m/s, time = 8 s. Calculate the distance traveled during the acceleration.

What is the acceleration of a car that maintains a constant velocity of 100km per h for 10 seconds?

Acceleration is the time rate of change of velocity. If velocity is constant, then acceleration is zero. Note: "100 km per h for 10 seconds" is a constant speed, but not necessarily a constant velocity, since we're told nothing about the direction. If the car moves in a perfectly straight line during those 10 seconds, then its velocity is constant. If it makes a curve, then its velocity is not constant even though its speed is, and there is acceleration.

What is the acceleration of the car during this time?

The acceleration of the car would be determined by dividing the change in velocity by the time taken. If the car started from rest and reached a speed of 30 m/s over 5 seconds, the acceleration would be 6 m/s^2.

Acceleration is defined as a change in velocity over time if a runner increases velocity from 2 m s to 4 m s over a period of 20 seconds what is the acceleration?

Assuming that acceleration is constant during that time, just divide the change in speed by the time.

What is the acceleration of a car that slows down from 60 ms to 40 m s during a period of 10 seconds?

-2 m/s^2

Difference between static and dynamic charercteristic of motor?

I think you are talking about the study of the electrical system for motor starting in ETAP (or any such software). Here are the answers:1. When do we use Static and Dynamic motor starting?If you know the Motor torque characteristics, Load torque characteristics and the inertia information of the motors, bearings and loads, you can do the Dynamic motor starting study. Otherwise, do the Static motor starting study - it simply needs the starting time and the locked rotor current of the motor.2. What is the difference between the two?(1) The Dynamic motor starting develops the motor starting current characteristics based on the motor starting torque, load torque and the inertia, while the starting current remains flat at locked rotor current during the starting time for Static acceleration. (See the previous posting http://cr4.globalspec.com/thread/42981 , comment # 2 for detail how the starting time is calculated for Dynamic acceleration).(2) Dynamic starting acceleration requires additional data than the Static acceleration.(3) The Dynamic acceleration calculates the acceleration time and current from the input data, while the Static acceleration assumes you know the starting time and current.(4) For Dynamic acceleration, the starting current is not 100% flat during the starting time, but in Static acceleration it is flat.(5) Static acceleration is simple, Dynamic acceleration is rather complicated.3. Can we evaluate the system using Static only not dynamic?Yes. Make sure you have the correct information for motor locked rotor current and the stating time for the load.Go the ETAP tutorial site (http://www.etap.com/training/tutorials-training-videos.htm) and see the tutorial #12 (Dynamic Acceleration) and #13 (Static acceleration).curtesy msamd

What is the acceleration of a car that screeches to a stop if it takes 3 seconds to go from 36 meters per seconds to 0 meters per seconds?

The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Substituting the values, we get acceleration = (0 m/s - 36 m/s) / 3 s = -36 m/s^2. Therefore, the acceleration of the car while stopping is -36 m/s^2.
