A rock is tossed straight up with a velocity of 16m/s When it returns, it falls into a hole 10m deep.
1) What is the rock's velocity as it hits the bottom of the hole? Express your answer with the appropriate units.
v=...............m/s?
2) How long is the rock in the air, from the instant it is released until it hits the bottom of the hole? Express your answer with the appropriate units.
t=..............s?
