The cricketer in the previous question hit the ball off the bat with a velocity
of 25 m/s at an angle of 38° above the horizontal. If the boundary is 60 m
away, work out whether the ball clears the boundary without bouncing or
not.

1. time in air:
hf=hi+25sin38*t-4.9t^2
hf=hi=0
solve for time in air t

nowHorizontal distance
d=25cos*t solve for d . Is it greater than 60?
