Can someone tell me what I'm doing wrong here:
A ball is thrown horizontally from the roof of a building 58 m tall and lands 35 m from the base. What was the ball's initial speed?
X0= 0m Y0= 0m
X= 58 m Y= 35 m
Vx=? Vy=0 m/s
Ax=0 m/s/s Ax=-9.8 m/s/s
T=?
35=0+0T-.5(-9.8)T^2
T=2.6 s
58=0+Vx(2.6)
Vx= 22 m/s <----------I know this is wrong
