Motion of Freely Falling Bodies
d = 0 m
d = 4.9 m
d = 19.6 m
d = 44.1 m
d = 78.4 m
d = 122.5 m
t = 3.0 s
d = ?
g = 10 m/s2
vo = ?
s ­ displacement (units: m)
v ­ final velocity (units: m s­¹)
u ­ initial velocity (units: m s­¹)
t ­ time duration (units: s) a ­ acceleration (m s­2)
All objects in free fall experience the same force of gravity ­ but do all ojects fall with an acceleration 0f 9.8 m/s2?

A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car and the distance traveled. A feather is dropped on the moon from a height of 1.40 meters. The acceleration of gravity on the moon is 1.67 m/s2. Determine the time for the feather to fall to the surface of the moon. With what speed must an object be thrown to reach a height of 91.5 m (equivalent to one football field)? Assume negligible air resistance. Oct 12­10:21 AM
