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 the acceleration of a truck if it accelerates from rest to 18mpers in 30s?
v = u + at a = (v - u) / t u = 0 , v = 18 ms-1 , t = 30 s a = 18 / 30 = 0.6 ms-2
What is gravity speed?
Gravity doesn't have speed , it has acceleration. On Earth gravitational acceleration is 9.8 ms^-2. Often approximated to 10 ms^-2
What is the acceleration when a car moving north goes from 5.56 ms to 63.9 ms in 7.5 s?
acceleration=(final velocity-initial velocity) divided by t a=Δv/t a=(63.9-5.56)/7.5 a=58.34/7.5 a=7.778666667≈7.8 meters per second squared (m/s2)
What describes a train's acceleration if it changes speed from 25 ms to 10 ms in 240 s?
Since the direction of motion is not given, nor implied by speed, the acceleration can have any value between 0.146 ms-2 and 0.0625 ms-2.
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.

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
If a cars velocity changes from 0 ms to 30 ms 10 seconds later its average acceleration is?
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2
What undergoing acceleration does an object change its speed from 10 ms to 3 ms?
Positive acceleration!(:
If the speeding train hits the brakes and it takes the train 39 seconds to go from 54.8 ms to 12 ms what is the acceleration?
if a speending train hits the brakes and it take the train 39bseconds to go from 54.8 m/s to 12 m/s what is the acceleration
What is the acceleration of a truck if it accelerates from rest to 18mpers in 30s?
v = u + at a = (v - u) / t u = 0 , v = 18 ms-1 , t = 30 s a = 18 / 30 = 0.6 ms-2
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 is the acceleration speed if you go from standing still to running 11 ms in 5 seconds?
The average rate of acceleration is (11/5) = 2.2 m/sec2 .
The velocity of a car changes from 10 ms to the east to 30 ms to the east in 4 seconds What is the acceleration of the car?
Average acceleration = (amount of change in speed velocity) / (time for the change) = (30 - 10) / (4) = 5 meters per second2 to the east
A car traveling in a straight line has a velocity of 5.0 ms After an acceleration of 0.75 ms squared the cars velocity is 8.0 ms In what time interval did the acceleration occur?
4.0 s
What is gravity speed?
Gravity doesn't have speed , it has acceleration. On Earth gravitational acceleration is 9.8 ms^-2. Often approximated to 10 ms^-2
