A ball is thrown vertically upward with an initial velocity of 25 m/s. Calculate: a) The maximum height the ball will reach. b) The time it takes for the ball to reach its maximum height. c) The total time of flight (up and down) for the ball. A skateboarder starts from rest and accelerates uniformly at 2.5 m/s² for 8 seconds. After that, the skateboarder continues at a constant velocity for an additional 5 seconds before coming to a stop. Determine: a) The maximum speed reached by the skateboarder. b) The total distance traveled during the entire motion.
