A tennis player strikes a tennis ball from underneath with her racket. The ball is sent straight up with an initial velocity of 19 m/s. How high above the striking point will the ball travel?
So the acceleration of gravity is 9.8 m/s so that’s how quickly it will accelerate downwards. You can use a kinematic equation to determine your answer. We know that initial velocity was 19 m/s, final velocity must be 0 m/s because it’s at the very top, and the acceleration is -9.8 m/s. You can then use this equation:
