Question
Suppose a projectile is fired from a cannon with velocity v and angle of elevation 0. The horizontal distance R (0) it travels (in feet) is given by the following.
(vo) sin 20
R(0) =
32
If v = 80 ft/s, what angle 0 (in radians) should be used to hit a target on the ground 114 feet in front of the cannon?
Do not round any intermediate computations, and round your answer(s) to the nearest hundredth of a radian. (If there is more than one answer, enter
