Choose the best answer to each question.

1. Which has the most kinetic energy?
A: A bowling ball with a velocity of 1.5 m/s.
2. Which has the most thermal energy?
A: A lake at 10*C.
3. Which has the least gravitational potential energy?
A: A 10 kg barbell resting on the floor.

The bowling ball

The lake

The barbell resting on the floor

Explanation:

I got it right on edge

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
