Explanation / Answer

Given v=19m/s, =45°, g=9.8m/s²
y = 2.3-3.05 = -0.75m

The time when ball reaches max height is given by:
t = (v/g)sin
=(19/9.8)*sin(45)
=1.64 s

The time when ball reaches the hoop is given by:
t = (v/g)sin+(1/g)((vsin)²+2gy)
= ((19/9.8)*sin(45))+((sqrt(19*0.85)^2+(2*9.8*0.75))/9.8)
= 4.79 s

The range (horiz length) of the shot is given by:
d = (v/g)cos(vsin+((vsin)²+2gy))
=  ((19/9.8)*cos(45)*(19*sin(45)+sqrt((19*sin(45))^2+2*9.8*0.75))
= 33.38 m
