Answer
A large truck and a small car are moving at the same speed, traveling up and down hills, and over bumpy roads. Which one has more kinetic energy?
(1 point)
• The truck has less kinetic energy because it has greater mass.


The car has more kinetic energy because it moves fast down hills.
The truck has more kinetic energy because it has a greater mass.
• The car and truck have the same kinetic energy.
Answer

• a yellow car with a mass of 500 kg moving at 12 m/s
Answer
A skydiver jumps out of a plane and begins to accelerate. His speed increases to 20 m/s, then 30 m/s. His acceleration slows until he reaches a constant speed of 50 m/s. Which statement accurately describes his kinetic energy while falling? (1 point)
His kinetic energy increased quickly at first, then it increased at a constant rate.
His kinetic energy was positive at first, but it decreased to zero when he stopped accelerating.
His kinetic energy increased while his speed increases, then it became constant.
His kinetic energy would remain the same for the whole fall as long as he lost no mass.
