directed downward

A ball tossed vertically upward rises, reaches its highest point, and then falls back to its starting point. During this time the acceleration of the ball is always

increasing

In each second of fall, the distance a freely falling object will fall is

5 m

Suppose a jumper claims a hang time of 2 s. Then that jumper must be able to jump a height of

is g no more no less

When a basketball player jumps to make a shot, once his or her feet are off the ground, the jumper's acceleration

less than the speed it had when thrown upwards

a ball is thrown upwards and caught when it comes back down. in the presence if air resistance, the speed with which it is caught is

is the same for each bullet

a bullet is dropped into a river from a very high bridge. at the same time, another bullet is fired from a gun, straight down towards the water. Neglecting air resistance, the acceleration just before striking the water

velocity increases

as an object freely falls its...

continually change by the same amount each second

if an object falls with constant acceleration, the velocity of the object must

0

what i the acceleration of a car that maintains a constant velocity of 100 km/h for 10 s?

zero and its acceleration is about 10/m/s/s

when a rock thrown straight upwards gets to the exact top of its path, its velocity is
