Question

car is moving with uniform velocity of 20 m/s second what is the kinetic energy of a boy of mass 80 kg sitting in the car​

Answer 1

Answer:

Given information:

m=80 kg

v=20m/s

We know that kinetic energy is given by :

K=1/2 * m * v²

K=1/2 * 80 * 20 * 20

K = 1600 joules or 1.6 kilojoule
