Q1. A ball is launched with the speed of 20.0m/s at 30 angle from point A at the top of a 100m tall cliff. The ball reaches a maximum height of 20m above the top of the cliff before falling to the ground at point B. Neglect air resistance. a. Sketch the motion, coordinates, known quantities and your plan? b. What will be the y component of the velocity at the maximum height position? c. What are the x and y components of the initial velocity? d. How long (time) to reach top from initial point A? What is the total time to reach ground point B? е.
