A ball is thrown straight up with an initial speed of v m/s. The ball was released 1.2 m above the ground, but when it returns back down, it falls into a hole 14.2 m deep. If the ball’s speed at the bottom of the hole is 28 m/s, what was the initial speed v (in m/s) of the ball?

A ball is thrown vertically upwards at a speed of 15m/s at the edge of a 20m deep well. The ball is released at a height of 2m above ground level. How high does the ball rise above ground level? If the ball on its downward path falls down the well, how many seconds elapse between releasing the ball and it striking the bottom of the well? Assume that the downward acceleration is 9.81 m/s2 .
