An h1 = 2.13 m tall basketball player wants to make a basket from a distance d = 10.8 m, as seen in the figure.
If he shoots the ball at α = 47.2° angle, at what initial speed must he throw the basketball so that it goes through the hoop without striking the backboard? The height of the basketball hoop is h2 = 3.05 m.
1/2((gd^2)/((cos(theta)^2 * ((H1-H2) +(d * tan(theta))) = Vo^2
The Attempt at a Solution
I have absolutely no idea how to use that equation. I was horrible and dropped my trig class and in doing so completely forgot how to use equations with theta. Any help is greatly appreciated.
