Question

Calculate the kinetic energy of a body of mass 4 kg moving with a velocity of 0.2 m/s.​

Answer 1

Answer:

mass of body = 4 kg

velocity of body = 0.2 m/s

kinetic energy = ½ mv²

KE = ½ × 4 × (0.2)²

KE = 2 × 0.04

KE = 0.08 joules

hence, kinetic energy of the body is 0.08 joules.

Answer 2

Answer:

icalculate kinetic energy of a body of a mass 4kg moving with a velocity of 0.2m/s. if the velocity doubled what will be the new kinetic energy.
