Step 1

Given information:

The mass of the bullet (mb) = 3.18 g = 0.0038 kg

The bass of the tennis ball (mt) = 58.4 g = 0.0584 kg

The velocity of the bullet (vb) = 1.5 ×103 m/s

Let the velocity of the tennis ball = vt

Step 2

Given the ball and the bullet have the same momentum hence we can write:

Step 3

The kinetic energy of the ...
