Velocity Q

[Haftred]

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?

[da_willem]

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.

[da_willem]

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.

K, you are right, I was trying to be too accurate...over such an obvious thing. :blush:
