A baseball is hit into the air at an initial speed of 36.6m/s and an angle of 50.0 degrees above the horizontal. At the same time, the center fielder starts running away from the batter and catches the ball 0.914m above the level at which it was hit. If the center fielder is initially 1.10 x 10^2m from the home plate, what must be his average speed?

An Olympic long jumper leaves the ground at an angle of 23 degrees and travels through the air for a horizontal distance of 8.7m before landing. What is the takeoff speed of the jumper?

A diver runs horizontally with a speed of 1.20m/s off a platform that is 10.0m above the water. What is his speed just before striking the water?
May someone help me, por favor. :)
