a)
Initial Horizontal and Vertical Components of Velocities are
Vox=22.6Cos51
Voy=22.6Sin51
Total time of flight is
t=X/Vox=36/22.6Cos51 = 2.53 s
From Kinematic equation
Y=Yo+Voyt-(1/2)gt2
Y=0+(22.6Sin51)(2.53)-(1/2)(9.81)(2.53)2
Y=13.03 m
Therefore the ball clears the post by
H=13.03-3.05 =9.98 m
b)
falling
Since time taken to reach maximum height
Vfy=Voy-gt
at maximum height Vfy=0
0=(22.6Sin51)-9.81t
t=1.79 s
Therefore the ball clears the post while falling
