An object is thrown vertically upwards with an initial velocity of 24 m/s from the edge of a cliff that is 50 m from the sea below, as shown in the figure. Determine the ball's maximum height hmax relative to the sea. Find the time taken for the ball to reach its maximum height. Determine the time to hit the sea. What is the velocity v(t) with which it hits the sea. Calculate the average velocity vavg during the interval t = 1.4 → 3.3 s. Calculate the average velocity vavg for the entire motion.
