DQuestion 9 10 pts Courses Inbox 10.0 m Help A 2.07 m tall basketball player is standing on the floor 8 m from the basket, similar to the pic shown. If he shoots the ball at a 33 degree angle with the horizontal, at what initial speed must he throw the basketball so that it goes through the hoop without striking the backboard? The height of the basket is 3.4 m. An app default was reset An app caused a problem with the default app setting for .png files, so it was reset to Photos. Question 10 5 pts -52 AM Search Windows ^ 4 11/29/2017Explanation / Answer
in horizontal, 8 = (v cos33)t
v t = 9.54 ..... (i)
in vertical,
yf -yi = v0y t + ay t^2 /2
3.4 - 2.07 = (v sin33)t - 9.8 t^2 /2
putting vt from (i)
1.33 = 9.54 sin33 - 4.9 t^2
1.33 = 5.195 - 4.9 t^2
t = 0.888 sec
putting in(i)
v = 10.7 m/s .........Ans
