**1. Homework Statement**

A spherical bowling ball with mass m = 3.2 kg and radius R = 0.112 m is thrown down the lane with an initial speed of v = 8.1 m/s. The coefficient of kinetic friction between the sliding ball and the ground is μ = 0.32. Once the ball begins to roll without slipping it moves with a constant velocity down the lane.

Q:What is the magnitude of the final velocity?

**2. Homework Equations**

Conservation of Momentum

Conservation of Energy

**3. The Attempt at a Solution**

Just want to check should i use both Conservation of Momentum and Conservation of Energy to find the final velocity?

Is there a shorter formula to find final velocity?
