Homework Help: About velocity

  1. Mar 21, 2015 #1
    1. The problem statement, all variables and given/known data
    A 0.160-kg hockey puck is moving on an icy, frictionless, horizontal surface. At t=0 the puck is moving to the right at 2.98m/s .

    2. Relevant equations

    Calculate the magnitude of the velocity of the puck after a force of 24.0N directed to the right has been applied for 5.5×10−2s .
    If instead, a force of 12.5N directed to the left is applied from t=0 to t= 5.5×10−2s , what is the magnitude of the final velocity of the puck?
    3. The attempt at a solution

    nosh, no help can be given unless you provide an attempt. What equations do you know that are relevant to the problem? What concepts are involved?
