Question

A body of mass m with s velocity of 5ms_1 possesses kinetic energy of 125joules.calculate mass

Answer 1

Answer:

Given,v (velocity) = 5m/s

Kinetic Energy =125J

To find: M (mass)

We know that

Kinetic energy =1/2Mv^2

Therefore,

125= 1/2M(5)^2

125=1/2M*25

250=25M

250/25=M

M= 10Kg
