An object with mass of grams is accelerated at m/s^{2}. The net force acting on the mass is how many newtons.

2

If a kilogram object moves meters in seconds at a constant speed, its momentum is how many kg m/s?

3

A force of newtons acts on a 4 kilogram object for seconds. How many newtons, acting for seconds will produce the same change in momentum?

4

An elevator weighs newtons. It is raised a vertical distance of meters in 15 seconds. How much work was done (in joules)?

A baseball bat strikes a ball with an average force of 20000 newtons. If the bat stays in contact with the ball for a distance of meter, how many joules of kinetic energy will be transferred to the ball?
