Velocity Q

  1. Aug 28, 2004 #1
    This might be a stupid question, but if a helicopter is moving at 5.0 m/s vertically, and one drops a ball off the helicopter, what is the original velocity of the ball?

    5m/s... relative to the ground and it will be in rest relative to the helicopter. Ofcourse only a splitsecond later this will not be true and the ball will accellerate under the influence of gravity.

    5.0m/s upward.

    Only if the helicopter was moving upward. The original post said vertically, so you don't know if it's moving upward or downwards.
