Dynamics: Newton’s Laws of Motion
A stone is thrown straight up. At the top of its path, the net force acting on it is:
An object sits on a frictionless surface. A 16-N force is applied to the object, and it accelerates at 2.0 m/s2. What is the mass of the object?

A student pulls a box of books on a smooth horizontal floor with a force of 100 N in a direction of 370 above the horizontal. If the mass of the box and the books is 40.0 kg, what is the acceleration of the box?

Two cars collide head-on. At every moment during the collision, the magnitude of the force the first car exerts on the second is exactly equal to the magnitude of the force the second car exerts on the first. This is an example of:

A block of mass m slides down a frictionless plane inclined at an angle θ with the horizontal. The normal reaction force exerted by the plane on the block is:
