Hello, Can you please help me with the following questions?

1. Consider a 250m high cliff. Suppose a boulder breaks loose from top of this cliff. How fast will it be going when it strikes the ground?

2. Calculate the height of a cliff if it takes 2.35s for rock to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.00 m/s.

3. A person standing on the edge of the cliff throws a rock straight up with initial velocity of 10 m/s. Calculate the position and velocity of the rock at 0.5s, 1.00 s, 1.50s, 2.00s and 2.50s after it is thrown. The point of release y0 = 0. Note down the values obtained after calculation in the data table given in the worksheet. Plot the position-time, velocity-time and acceleration-time graph based on the obtained data.
