2. A rock is tossed straight up with a velocity of 23 m/s When it returns, it falls into a hole 10m deep.

Part A. What is the rock's velocity as it hits the bottom of the hole?
Part B. How long is the rock in the air, from the instant it is released until it hits the bottom of the hole?

A particle moving along the x-axis has its position described by the function x =( 3.00 t^{3}- 5.00 t+ 5.00 )\; {\rm m}, where t is in s. At t= 4.00, what are the particle's (a) position, (b) velocity, and (c) acceleration?
