A baseball is thrown with an initial velocity of 30 m/s at an angle of 30° above the horizontal. What is the highest point the ball will reach?

As part of an athlete’s rehab, you are testing the athlete’s performance on a test called “fly in sprints.” After a running start, you measure how quickly the athlete is able to complete the run. You determine that the athlete has an initial velocity of 5 m/s, and the athlete accelerates at a rate of 2.5 m/s2 over the 3 s it takes to complete the sprint. What was the athlete’s velocity at the end of the test?
