I need a 1.00 W motor to push a garbage compactor so that it squishes some garbage. The garbage has a spring constant of 49.7 N/m. If I am going to squish it 30 cm, determine how much time the compactor takes.

  1. Average force = Fav
    = (1/2)*49.7 N/m*(0.30 m)
    = 7.46 N
    Work = Fav*X = 2.24 J
    Power*T = 2.24 J
    T = 2.24 seconds

  2. thats not right. you forgot to square the x value. 0.30 should have been 0.09
