# A cycle together with its rider weighs 100kg. How much work is needed to set it moving at 3 m/s.

Answer :

The energy required is kinetic energy of the cycle together with its rider

Given data :

mass (m) = 100kg

velocity (v) = 3 m/s

Kinetic Energy is given by the formula Putting the given values in the formula ,we have

100 = 450 J
