8. A person kicks a ball such that it leaves the ground with an initial velocity of20.0 m/s at an angle of 53.0° above the horizontal. The ball travels 36.0 metershorizontally where it clears a bar that is 3.05 meters above the ground. (a) Bywhat distance does the ball clear the bar? (b) What is the velocity in the y-direction of the ball when directly above the bar?Answers: (a) 0.85 m (b) -13.4 j m/s

Given: velocity v=20 m/s θ=53 distance,d=36 m above ground h=3.05 m
