Uniform Circular Motion and Projectile All-in-One

  1. Apr 1, 2015 #1
    1. The problem statement, all variables and given/known data\
    Joey spins a laptop then he releases it, at an angle. Assuming no wind resistance, the laptop (has a rubberized case) hits the concrete and drags across the concrete for 5.3 seconds. What is the coefficient of friction between the rubber and concrete and what distance does it travel?

    2. Relevant equations
    Is there sufficient amount of information in this question to be able to solve it? If not, any suggestions on what to add to be able to solve it?

    3. The attempt at a solution

    Hello Suzana, welcome to PF :smile: !

    I can follow the problem statement, but I don't see any relevant equations. If you have unknowns, you need equations. You need as many equations as you have unknowns, so you better start gathering some.
    Then you start with an attempt at solution and then you can expect some help on PF. That's the way it works here, can't help it :rolleyes: . But there's good reasons for rules like that.
