A 0.01 kg Styrofoam ball is released from rest 2m above the floor. It reaches a speed of 3m/s the moment before it hits the floor. How much heat due to air resistance is generated during this process?

  1. fall from 2 meters
    potential energy loss = m g h =.01 *9.81*2
    = .1962 Joules
    kinetic energy gain = (1/2)mv^2 =.005(9)
    =.045 Joules

    difference is lost to heat
    .1962 - .045 = .151 Joules
