Question

A car of mass 500kg is moving with a velocity of 40m/s.calculate kinetice energy

Answer 1

Answer

400 KJ

Explanation:

m =  500 kg

v = 40 m/s

Kinetic Energy = $\frac{1}{2}$ $mv^{2}$

                         = $\frac{1}{2}$ 500 * $40^{2}$

                          = 400000 J

                          = 400 KJ
