Homework Help: Bowling Ball

  1. Mar 12, 2012 #1
    1. The problem statement, all variables and given/known data

    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. Relevant 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?

    hi ctwokay! :wink:
    how can you use conservation of momentum? :confused:

    use the work-energy theorem :smile:
