A bullet with a mass of 3.18 g moves at a speed of 1.50 ✕ 10^{3} m/s. If a tennis ball of mass 58.4 g has the same momentum as the bullet, what is its speed (in m/s)?

Step 1

**Given information:**

The mass of the bullet (m_{b}) = 3.18 g = 0.0038 kg

The bass of the tennis ball (m_{t}) = 58.4 g = 0.0584 kg

The velocity of the bullet (v_{b}) = 1.5 ×10^{3} m/s

Let the velocity of the tennis ball = v_{t}

Step 2

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

Step 3

The kinetic energy of the ...
