A baseball player hits a ball at a speed of 34 m/s at an angle of 30. When the ball hits the bat, it is 1.2 m above the ground. An outfielder positions himself 98 m from where the ball was struck, and the ball flies over his head.

a. At what time does the ball pass over the outfielder's head? (1 point)

b. Standing straight up, the outfielder can raise his glove to a height of 2.3 m. How high does the ball fly over the outfielder's glove? (1 point)

c. He can jump upward at a speed of 7 m/s. At what time after the ball is hit should he jump so that his glove intersects the path of the ball? (1 point)

d. Why are there two possible solutions for part (c)? (1 point)
