Question

Divers at Acapulco dive from a cliff that is 60 m high. If the rocks below the cliff extend outward for 23 m, what is the minimum horizontal velocity a diver must have to clear the rocks safely?

Answer 1

You are at a Marlins baseball game with your friend, who won a pair of tickets for seats just behind the right field wall 120 m from home plate. Jose Reyes hits a long fly ball at a 41.0° angle from the horizontal and you catch it 3.59 s later for a home run. What was the inital speed with which the ball was hit? (m/s)
