A ball is thrown vertically upward with an initial speed of 15 m/s from 80 m above the ground. Assume free fall conditions. (a) What is the max height? (b) Determine the magnitude of the velocity at 40 m above ground. (c) At what speed does the ball strike the ground?
Okay, let's start with part (a). What is the maximum height for the ball?
Using the equations of motion, we can calculate that the maximum height is 132.375 meters.
