Afew years ago, serena williams dived to hit a tennis ball right after it bounced off the ground. the ball bounced on the ground 11.7 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 1.21 s after she hit it. if there had been no gravity, the ball would have been 2.63 m higher than the net when it crossed over. how fast was the ball moving when it left serena's racket?
