Homework Help: Momentum at maximum height

  1. Nov 12, 2007 #1
    1. The problem statement, all variables and given/known data

    A 0.15kg ball of dough is thrown straight up into the air with an initial speed of 17 m/s. The acceleration due to gravity is 9.81 m/s^2. What is its momentum at its maximum height?

    2. Relevant equations

    momentum=mass X velocity

    change in momentum= mass (FinalVelocity - InitialVelocity)

    3. The attempt at a solution

    momentum = (0.15)(VF - 17)

    but there are two unknowns, i'm not even sure thats what the problem is asking for though...

    In this and your previous momentum questions, you keep referencing 'change in momentum' in your relevant equations,yet the problems do not ask for momentum change, they just ask for momentum. In this problem, what is the velocity of the ball when it reaches its maximum height?
