A few years ago, Serena Williams dived to hit a tennis ball right after it bounced off the ground. The ball bounced on the ground 10.5 m from the net, and after Serena hit the ball it flew over the 0.950 m high net and bounced in her opponent's court about 1.07 s after she hit it. If there had been no gravity, the ball would have been 1.88 m higher than the net when it crossed over.

How fast was the ball moving when it left Serena's racket? Ignore any effects from ball spin and air resistance.

Expert Solution
