How do you Calculate the power output of a Person that bench presses 150 pounds 30 times in 10 seconds and moves the barbell a distance of 24 inches during each press?
Power is defined as work over time. Thus, we must first calculate the work involved in moving the barbell. W = Fd = 150 lbs * 2 ft = 300 ft-lbs per rep The work expended over the entire work out is thus 30 * 300 ft-lbs = 9000 ft-lbs. Since P = W/t, the power output is P = 9000 ft-lbs/10s = 900 ft-lbs/sec, which is about 1222 watts.
What else can I help you with?
The weight lifter used a force of 980N to raise the barbell over her head in 521 seconds approximately how much work did she do in raising the barbell?
5105.8 J
An object uniformly accelerates over a distance of 100 m in 20 seconds. What is the acceleration?
an object uniformly accerlerates over a distance of 100 m in 20 seconds. calculate the acceleration.
What is the speed of an object 10m from you for 2 seconds?
To calculate the speed of an object, we need to know the distance it travels and the time it takes. If the object is 10m away from you and travels that distance in 2 seconds, we can calculate its speed using the formula: Speed = Distance/Time. In this case, Speed = 10m/2s = 5 m/s.
How do you calculate the distance of a lightning flash?
Look for the lightning flash, and count the seconds until the thunder is heard. Every 5 seconds equals one mile of distance. While the light appears almost instantly sound travels at about 1200 fps, or roughly 5 seconds per mile. In metric units the speed of sound in air is approximately 330 m/s so every 3 seconds is roughly equivalent to 1 km.
What is the power expended when a barbell is lifted 2.2m in 2 seconds?
The power during the lift is (weight of the barbell in Newtons)/4.4 watts.Note:Power is not "expended". Energy is. Power is the rate at which energy is expended.
How do you calculate speed in miles per second?
The distance travelled, measured in miles divided by the time taken, measured in seconds.
How fast is 200 feet In 6 seconds?
22.73 mph
If you are given the mass of an object in pounds the time in seconds and the distance in feet what must you do before you can calculate the momentum in SI units?
You must convert the mass from pounds to kilograms, time from seconds to seconds, and distance from feet to meters. Only then can you use the formula for momentum (momentum = mass * velocity) to calculate momentum in SI units (kg*m/s).
How do you calculate the speed in meters per second (m/s)?
To calculate speed in meters per second (m/s), you divide the distance traveled in meters by the time taken to travel that distance in seconds. The formula is: Speed (m/s) Distance (m) / Time (s).
How do you calculate your average speed for a 100 M?
To calculate your average speed for a 100 meters run, divide the total distance by the total time taken to complete the distance. The formula is: Average Speed = Distance / Time. For example, if you run 100 meters in 12 seconds, your average speed would be 100 meters / 12 seconds, which equals approximately 8.33 meters per second.
How do you calculate seconds when given meters per second?
You can't convert between seconds, and meters/second. If you have a problem that involves speeds, use the formula: distance = speed x time.
What is the average speed from 4s to 8s?
To find the average speed from 4 seconds to 8 seconds, you need the total distance traveled during that time interval and the total time taken. The average speed is calculated by dividing the total distance by the total time (4 seconds in this case). If you provide the distance traveled during that period, I can help you calculate the average speed.
