Q. 22

Calculate the kinetic energy of a body of mass 50 Kg moving with a velocity of 50 cm

Answer :

Given,

Mass m = 50 kg


Velocity = 50 cms-1


1 cm = 0.01 m


So, velocity = 50 ×0.01 ms-1


v = 0.5 ms-1


We know,


Kinetic energy = m v2


Substituting value of m and v in the equation:


Kinetic energy =


= kgm2s-2


= 6 J
