Problem 55P
IP A golfer tees off on level ground, giving the ball an initial speed of 46.5 m/s and an initial direction of 37.5° above the horizontal, (a) How far from the golfer does the ball land? (b) The next golfer in the group hits a ball with the same initial speed but at an angle above the horizontal that is greater than 45.0°. Tf the second ball travels the same horizontal distance as the first ball, what was its initial direction of motion? Explain.
ANSWER:
a.)
Step 1 of 2
We have to find how far from the golfer does the ball land.
The distance at which the ball falls from the golfer can be found using the expression,
where,
initial speed of the ball = 46.5 m/s
initial direction of the ball = 37.5o
9.81 m/s2
Hence,
= 213 m
Therefore, the ball falls at a distance of 213 m from the golfer.
b.)
