Homework Statement
Ok I am having slight trouble with a homework problem. An arrow was launched at an angle, and hit a balloon that was 150m away and 100m up. I used my distance equations along with initial velocity to calculate the two angles that can be used to hit the balloon, but I'm stuck on the next part. I used t=dx/vx to solve for time, and now I need to solve for the velocity when the arrow hits the balloon. I'm sure it's a simple problem but I'm stuck!
Initial Velocity=60m/s
Distance from 0=150m
Height in Y direction=100m
dy=Voy(t)-4.9t^2
Vx=Vcos(x)
Vy=Vsin(x)
t=dx/vx
I used the four equations above to solve for the angle(s). Then put in the velocities to solve for time. How do I solve for velocity when the arrow hits the balloon?
