A basketball player shoots a ball at an angle of 55(adsbygoogle = window.adsbygoogle || []).push({}); ^{o}into a hoop and lands in the net, which is 3.0m off the ground. Calculate the initial speed of the ball for this fould shot to be successful.

I did some vector integration and then isolated each of the components:

V_{x}= vcos55

V_{y}= vsin55 - gt

s_{x}= vcos55t

s_{y}= vsin55t - gt^{2}/2 + 2.1

When

s_{y}= vsin55t - gt^{2}/2 + 2.1 = 3

s_{x}= vcos55t = 4.3

However, even after some manipulating, there are two variables and I can't isolate any of them. Or maybe I am just missing something?
