Question

Velocity of the ball A after collision with the ball b as shown in the figure is (assume perfectly inelastic and head on collision)

Answer 1

Explanation:

Aloha !

If collision takes place between two balls. If u1 is speed of one ball and u2 is speed of another ball after collision v1 and V2 will be the speeds.

Thank you

Answer 2

Answer:

Velocity of the ball A after collision is 0 m/s.

Explanation:

Given;-

      Mass of ball A = 2 kg

       Mass of ball B = 5 kg

Initial Velocity of ball A = 5 m/s

Initial Velocity of ball B = 2 m/s

We know that, for perfectly elastic and head on collision, the common velocity after collision is given by;-

           v = m₁u₁ + m₂u₂ / m₁+m₂

Putting the given values in the formula, we get:-

           v = 2 ×5 + (-5)×2/ 5 + 2

           v = 10 - 10/ 7

           v = 0/7

          v = 0 m/s

Hope it helps! ;-))
