A ball is thrown vertically upwards with an initial velocity of 10 m/s, from a platform that is at a height of 75 m above the ground. The ball reaches a maximum height and, on the way down, misses the platform and falls all the way to the ground. Take the magnitude of the acceleration due to gravity to be 10 m/s2. (a) What is the velocity of the ball just before it reaches the ground? (b) How many seconds...

I throw a ball straight upward at an initial velocity of +40 m/s. Assuming g is -10 m/s2, (a) how long would it take for the ball to reach its maximum height before falling back down? (b) what will its final speed be right before reaching your hand again at the same height as where you threw it? (c) how does the acceleration of the ball change as it reaches the top of its path going 0 m/s?
