Question

What is the kinetic energy of a bicycle with a mass of 14 kg traveling at a velocity of 3 /s

Answer 1

Remember that the formula for kinetic energy is:
Kinetic energy = 1/2 mv²

KE = 1/2 * 14 kg * (3 m/s)²
KE = 7 kg * 9m²/s²
KE = 63 kg*m/s² * m
KE = 63 N*m
KE = 63 J

The kinetic energy of the bicycle is 63 joules.
