hi guys
tnx for ur helps in this great forum, i just encountered another question which i cant solve it from the first part i just could just analyse it! how can i put this numbers in proper equation?

A major leaguer hits a baseball so that it leaves the bat at a speed of 28.4 m/s and at an angle of 36.0^\circ above the horizontal. You can ignore air resistance.


At what two times is the baseball at a height of 10.1 m above the point at which it left the bat?


Calculate the horizontal component of the baseball's velocity at an earlier time calculated in part


Calculate the vertical component of the baseball's velocity at an earlier time calculated in part (a).

Calculate the horizontal component of the baseball's velocity at a later time calculated in part (a).

Calculate the vertical component of the baseball's velocity at a later time calculated in part (a).


What is the magnitude of the baseball's velocity when it returns to the level at which it left the bat?


What is the direction of the baseball's velocity when it returns to the level at which it left the bat?
