Exam 3: Equilibrium and Linear Motion

If a car increases its velocity from zero to 60 km/h in 10 seconds, its acceleration is

If an object falling freely were somehow equipped with an odometer to measure the distance it travels, then the amount of distance it travels each succeeding second would be

A bullet is dropped from the top of the Empire State Building while another bullet is fired downward from the same location. Neglecting air resistance, the acceleration of

Disregarding air resistance, objects fall with constant

An apple falls from a tree and hits the ground 5 meters below. It hits the ground with a speed of about

An object covers a distance of 8 meters in the first second of travel, another 8 meters during the next second , and 8 meters again during the third second. Its acceleration in meters per second per Second is approximately

A man leans over the edge of a cliff and throws a rock upward at 4.9 m/s. Neglecting air resistance, one second later the rock's speed is

A ball is thrown upwards. Neglecting air resistance, what initial upward speed does the ball need to remain in the air for a total time of 10 seconds?

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

At one instant a heavy object in air is moving upward at 50 meters per second. One second later its speed in meters per second is approximately

If a car accelerates from rest at 2 meters per second per second, its speed 3 seconds later will be about

An object falls freely from rest on a planet where the acceleration due to gravity is twice as much as it is on Earth. In the first 5 seconds it falls a distance of

A man leans over the edge of a cliff and throws a rock upward at 4.9 m/s. How far below the level from which it was thrown is the rock 2 seconds later?

The vertical height attained by a basketball player who achieves a hang time of a full 1 s is
