so 14+4cos45*2=18.2 -> 4sin45-(g*18.2/4cos45)?

v_y=vsin0-(gx/vcos0)

xt=x0 + v0 cos(a) t y(t) = y0 + v0 sin(a) t - (1/2) g t^2 i don't understand what is meant by v_y(t)

Homework Statement I don't know what equation to use. i am trying to find out the velocity need to make a shot. the conditions are ideal. initial height: 6 feet initial vertical velocity:unknown angle of trajectory: 45 degrees range: 14 feet time:2 seconds basketball hoop height: 10...
