(a) What initial vertical velocity (in m/s) does he need to rise to a maximum height 3 meters above the floor? (b) How far (in m) from the basket (measured in the horizontal direction) must he start his jump to reach his maximum height at the same time as he reaches the basket?

- A baseball player hits a baseball when it’s 1m above the ground giving it an initial velocityof 61m/s at 18◦ above the horizontal. The catchers on the other team are very good at theirjobs and have a 100% success rate, so a homerun can only be achieved if the batter hits theball over a 2m fence 75m away from the plate.
