L. A boy of mass 40 kg is running with a velocity of 0.5 ms. What is his kinetic energy?​

Answer 1

Answer:

5Joules

Explanation:

Given:

Mass (M)= 40kg

Velocity (v)=0.5m/s

Kinetic energy (K.E)=?

Kinetic energy (K.E)= 1/2mv²

Kinetic energy (K.E)= 1/2 x 40 x 0.5²

= 20 x 0.25

=5Joules

I hope u understood how to solve the numerical.
