PHYSICS - free fall

the vertical height attained by a basketball player who achieves a hang time of 1 full second is about

1.2 m

Ten seconds after starting from rest, a freely falling object will have a speed of about:

100m/s

If a projectile is fired straight up at a speed of 10 m/s, the total time to return to its starting point is about

2 seconds

if an object were equipped with a speedometer and allowed to fall freely on a planet where acceleration due to gravity is 20m/s2, the reading on the speedometer would increase each second by:

20m/s

Suppose a jumper claims a hang time of 2 seconds. Then that jumper must be able to jump a vertical distance of:

5m

One half-second after starting from rest, a freely falling object will have a speed of about:

5m/s

Suppose an object is in free fall. Each second the object falls-

a larger or smaller distance than the second before

If a freely falling object were somehow equipped with a speedometer, its speed reading would increase each second by

about 10 m/s

in the absence of air resistance, objects fall at constant:

acceleration

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:

directed downward

a ball is thrown upwards and caught when it comes back down. In the absence of air resistance, the speed of the ball when caught would be:

the same as the speed it had when thrown upwards

As an object falls freely in a vacuum, its

velocity increases!
