Answer:
Yes it is talking about more than one person
A. f(1) = 1 + 3 = 4
b. f(6) = 2*6 = 12
D because if it keep rotating it will never hit anything
The horizontal component of the velocity of the ball will be 100 cos 35 + 14
= 95.92 ft/sec.
The time for the ball to reach the fence = 120 / 95.92 = 1.251 seconds.
We now have to find the height of the ball after 1.251 seconds.
Vertical component of the velocity = 100 sin 35 = 57.36 ft/second
It has to be at a height of over 40 ft at time 1.251 seconds.
equation of motion is h = 57.36t - 16t^2 + 3
so we have h = 57.36(1.251) - 16(1.251)^2 + 3 = 49.7 feet
so (a) it will be a home run and
(b) it clears the fence by 9.7 feet.
