A rock is tossed straight up from ground level with a speed of 30 m/s. When it returns, it falls into a hole 35 m deep. What is the rock's velocity just before it hits the bottom hole? How long is the rock in the air, from the instant it is released until it hits the bottom of the hole? What is the total distance traveled by the rock from the point of throw to the point where it hits the bottom of the hole?

Question

I need help on this problem:

A rock is tossed straight up from ground level with a speed of 30 m/s. When it returns, it falls into a hole 35 m deep. What is the rock's velocity just before it hits the bottom hole? How long is the rock in the air, from the instant it is released until it hits the bottom of the hole? What is the total distance traveled by the rock from the point of throw to the point where it hits the bottom of the hole? Sketch the velocity versus time graph, position versus time graph, and distance covered versus time graph. (Vertical as y-axis).
