Please help me. Thank you.

Problem 1) Freely Falling Coin A coin is dropped from the Leaning Tower of Pisa and falls freely from rest. What are its position and velocity after 1.0s, 2.0s, 3.0s. How long will it take the coin to reach the ground, if the Leaning Tower of Pisa is 55.86m (which it is according to Google)? Problem 2) Up-and-down Motion in Free Fall You throw a ball vertically upward from the roof of a tall building. The ball leaves your hand at a point even with the edge of the roof with an upward speed of 15.0 m/s; the ball is then in free fall. On its way back down, it just misses the railing. a) Find the ball's position and velocity 1.00s and 4.00s after leaving your hand. b) Find the ball's velocity when it is 5.00m above the railing C) Find the maximum height reached by the ball. d What is the ball's acceleration when it is at its maximum height
