Question

a body of mass 10kg is travelling with uniform speed of 5m/s it kinematic energy is?

Answer 1

knetic energy=
$m {v}^{2} \\ 10 \times 5 \times 5 \\ 250 \: kg \: m \: per \: sec$

Answer 2

mass of the body = 10 kg
velocity = 5m / s
kinetic energy =1/2 m × v square
= 1/2 × 10 × 5×5
=5×25
=125 J
