Problema Solution
a golfer hits his T-shot along a flat fairway at 40 degrees to the horizontal with an initial spped of 150 feet per second.What is the range of the ball?
Answer provided by our tutors
We assume the time in the air is t, the range is S.
The vertical speed is 150*sin(40) = 96.42 ft/s
The horizontal speed is 150*cos(40) = 114.91 ft/s
So
t = 2*96.42/ 32.15 = 6 s
S = 114.91 ft/s * 6s = 689.5 ft
So the range is 689.5 ft.
