You throw a baseball to hit a target on the ground 10m from the base of a building 25m in height. (a) With what velocity must you throw the baseball if it is to leave the hand horizontally? (b) with what velocity mut you throw the baseball if it is to leave the hand at a angle of 45 up from the horizontal? (c0 What is the horizontal component of the initial value o the velocity in case (b)?

2. Relevant equations

(a) s=ut +1/2at^2

v=d/t

(b) i have no clue

(c) Vx(cos theta)

3. The attempt at a solution

(a)s=ut+1/2at^2

25=0+ 1/2(9.8)t^2

25= 4.9t^2

25/4.9=t^2

t=√5.10

t=2.26s

v=d/t

= 10/2.26s

=4.42m/s

(b) i don't know can someone point me in the right direction
