Question

A ball with a mass of 65 kg collides with a ball that has a mass of 112kg. It is an ellastic collision: Ball one is travelling at 8.0m/s, ball two is travelling the opposite direction at 3.00m/s.

b. Write the equation to express the conservation of momentum for the collision.

Expert Solution

Step 1

$G i v e n : m a s s, m_{1} = 65 k g m a s s, m_{2} = 112 k g V e l o c i t y, u_{1} = 8 m / s V e l o c i t y, u_{2} = - 3 m / s N o w, c o n s e r v a t i o n o f m o m e n t u m f o r t h e c o l l i s i o n . m_{1} u_{1} + m_{2} u_{2} = m_{1} v_{1} + m_{2} v_{2} (65 k g \times 8 m / s - 112 k g \times 3 m / s) = (65 k g \times V_{1} + 112 k g \times V_{2}) 184 = 65 V_{1} + 112 V_{2} . . . . (E q 1)$
