Question

In what factor does the kinetic energy change if the motorcycle speed drops to 34 miles per hour?

Initial: 68 mph

Answer 1

Answer #1

Answer:-

kinetic energy = 1/2mv²

initial = 68 mph

final = 34

so the velocity becomes half so, kinetic energy becomes 1/4th of the initial energy .

1/4 times of initial kinetic energy

Answer 2
