A sphere of mass 25 Kg is moving at a speed of 1.5 m/s undergoes collision with another sphere of mass 50 Kg moving at 3m/s in the same direction, find the loss of kinetic energy when the collision is inelastic.

(a) 18.75 N-m

(b) 19.75 N-m

(c) 17.75 N-m

(d) 16.75 N-m

The question was posed to me in final exam.

The question is from Loss of Kinetic Energy During Elastic Impact topic in chapter Kinematics & Kinetics of Motion of Machine Kinematics

Right choice is (a) 18.75 N-m

The explanation is: Loss of kinetic energy during inelastic collision is given by

m1m2/(2(m1+ m2) (u1^2 – u2^2)

substituting the values we get

El = 18.75 N-m.
