A skydiver slows down from 54 ms to 4 ms by opening his parachute. If this takes 0.75 seconds what is the magnitude of the skydiver's acceleration?
66.7 m/s2
What is a skydivers velocity after 2 seconds?
Acceleration due to gravity is 9.8m/s/s, which is the same as 9.8m/s2. An acceleration of 9.8m/s/s means that with each passing second, the velocity of the skydiver increases by 9.8m/s. Therefore, after two seconds. a skydiver's velocity would be 19.6m/s. The acceleration will continue at 9.8m/s/s until the skydiver reaches terminal velocity, at which point the weight of the skydiver and the air resistance will be balanced, so the net force acting on the skydiver will be zero, at which point there will be no further acceleration.
Why several seconds after jumping from an aircraft a skydiver will be travelling at a constant speed?
Because you reach maximum velocity.
What is the Order of Magnitude of the number of seconds in one hour?
101 is.
What is the skydiver's downward velocity after 2 seconds?
Assuming we neglect air resistance and start from rest in the vertical plane - use v=u+at so v = 0+(10x2) assuming g = 10N/kg =20m/s In practice it will be less because air resistance will tend to slow the skydiver down.
When skydiver slows down from 54 meters to 4 meters by opening his parachute If this takes 0.75 seconds what is the magnitude of the skydiver's acceleration?
the magnitude of the skydivers acceleration is zero as he is decelerating by opening his parachute!
A skydiver slows down from 54 ms to 4 ms by opening his parachute. If this takes 0.75 seconds what is the magnitude of the skydiver's acceleration?
66.7 m/s2
A skydiver slows down from 54 ms to 4 ms by opening his parachute If this takes 0.75 seconds what is the magnitude of the skydivers acceleration?
66.7 m/s2
Skydiver slows down from 65 ms to 5 ms by opening the parachute If this takes 0.75 seconds what is the skydiver's acceleration?
80 m/s 2 up
What is the skydiver's downward velocity?
Maximum speed is about 220 to 230mph and can be achieved after about 20 seconds of freefall. Normal parachute opening speed should be not greater that 120mph to avoid damage to the parachute
A skydiver slows down from 54 ms to 4 ms by opening his parachute. if it takes 0.75 seconds what is the magnitude of the skydiver's acceleration?
(4 m/s - 54 m/s)/0.75 s = -50/0.75 m/s² = -200/3 ≈ - 66.67 m/s² (negative because he is decelerating)
What A skydiver slows down from 54 ms to 4 ms by opening his parachute this change takes 0.75 what is the skydiver acceleration?
If the 0.75 refers to seconds, then his acceleration is -66.66... (repeating) metres per second^2.
What is the magnitude of a skydiver's acceleration if it takes 0.75 seconds?
zero
A skydiver slows down from 65 ms to 5 ms by opening the parachute If this takes 0.75 seconds what is the skydivers acceleration?
80 m/s2 up
A skydiver slows down from 65 ms by opening the parachute if this takes 0.75 seconds what is the skydivers acceration?
To calculate this, you divide the change in velocity, by the time.
When a skydiver jumps from an airplane the distance d in feet the diver falls in t seconds before opening the parachute is given by the formula Test Image. The formula assumes that there is no air res?
If d = 16*t^2 then there is no significant air resistance.
A skydiver slows down from 65 m s to 5 m s by opening the parachute If this takes 0.75 seconds what is the skydiver's acceleration?
The general formula for acceleration is [(final velocity) - (initial velocity)]/(time required for the change). In this instance, (5 - 65)/0.75 = -80 meters per second per second.
