Question

A major leaguer hits a baseball so that it leaves the bat at aspeed of 32.0 m/s and at an angle of36.9° above the horizontal. You can ignore air resistance.(Assume upward is positive.) (a) At what two times is the baseball at aheight of 11.0 m above the point atwhich it left the bat?
first time
(s) seconds
second time
(s) seconds

(b) Calculate the horizontal and vertical components of thebaseball's velocity at each of the two times calculated in part(a).
first time
m/s (horizontal component)
m/s (vertical component)
second time
m/s (horizontal component)
m/s (vertical component)

(c) What are the magnitude and direction of the baseball's velocitywhen it returns to the level at which it left the bat?
m/s
degree° (below the horizontal) (a) At what two times is the baseball at aheight of 11.0 m above the point atwhich it left the bat?
