If Andy is working in a warehouse and delivers two of the packages on his cart which statement would be correct?

• As the mass of the cart DECREASES, Andy needs to exert LESS force to maintain the same speed

• As the mass of the cart INCREASES, Andy needs to exert LESS force to maintain the same speed

• As the mass of the cart DECREASES, Andy needs to exert MORE force to maintain the same speed

• As the mass of the cart INCREASES, Andy needs to exert MORE force to maintain the same speed

A boy is riding his bike around a racetrack at a constant speed. After each lap he adds a brick to his backpack. As the mass of the boy on the bike increases, what happens to his kinetic energy?

• The bikes energy increases in an unpredictable way.

• The bikes energy decreases proportionally.

• The bikes kinetic energy decreases in a predictable way.

• The bike's kinetic energy increases in proportion to the change in the cart’s mass.
