A child weighing 4.50 x 102 N sits on a seesaw 0.60 m from the axis of rotation. How far from the axis of rotation on the other side should a child with a weight of 6.00 x 102 N sit so the seesaw will remain balanced?

Mass is a measure of an object’s resistance to: I. Turning II. Speeding Up III. Slowing Down  

A 1-kg block starts sliding up a frictionless 30o inclined plane with an initial velocity of 4.00 m/s. How far does the block go up the ramp before stopping?

An apple falls from a tree. How do its KE and GPE change as it falls to the ground?

A crate is attracted toward the center of the earth by a gravitational force of 500 N. The force with which the earth is attracted toward the crate is:

Suppose that 56 J of work was done to increase the kinetic energy of a 1.90-kg mass. If the object’s initial velocity was zero, what is its speed now?

The work required to accelerate an object initially at rest to a speed v0 is W. What is the additional work needed to increase its speed from v0 to 2v0?

A truck increases its speed from 8 m/s to 28 m/s over a distance of 120 m? How long does this take? Assume that the acceleration is constant.

A car starts from rest and reaches a speed of 50 m/s in 10 s. What is its average acceleration?

A car that is moving at a speed of 15 m/s is coming to a complete stop in 5.2 seconds. What is the acceleration of the car?
