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 velocity of 50 Kg mass in m/s after collision when the collision is elastic.
(a) 2.5
(b) 2.00
(c) 7.25
(d) 6.75
I had been asked this question in a dream while sleeping
My doubt stems from Loss of Kinetic Energy During Elastic Impact topic in section Kinematics & Kinetics of Motion of Machine Kinematics
