A basketball player 1.9 m tall wants to
make a basket from a distance of 7.8 m. The
hoop is at a height of 3.05 m.If he shoots the ball (from a height of 1.9 m)
at a 23.5 angle, at what initial speed must he
shoot the basketball so that it goes through
the hoop without striking the backboard?
The acceleration due to gravity is 9.8 m/s2 .
Neglect air friction.
Answer in units of m/s
