Which of the following is the best example of kinetic energy?

a book sitting on a bookshelf
a golfer preparing to putt the ball
a race car in position at the start line
a satellite orbiting the earth

A satellite orbiting the Earth

Explanation:

Kinetic energy is the intrinsic energy possessed by an object in motion.  The bigger the object in motion, and the higher its speed , the higher the kinetic energy. The equation below is used to calculate this energy also referred to as the work put into the object to accelerate it into its current velocity.

E(k) = 1/2 * m * v²

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

no. dot product   =0 when vecs at right angles
