Question

A completely inelastic collision occurs between two balls of wet putty that move directly toward each other along a vertical axis. Just before the collision, one ball, of mass 3.0 kg, is moving upward at 20 m/s and the other ball, of mass 2.0 kg, is moving downward at 12 m/s. How high do the combined two balls of putty rise above the collision point? (Neglect air drag.)

Answer 1

Mass of the first object (m₁) = 3.0 kg

Initial speed (V₁) = 20 m/s upward

Mass of the second object (m₂) = 2.0 kg

Intitial speed (V₂) = 12 m/s downward

   

The combined height attained by the balls..
