A cannon sends a projectile towards a target a distance 1210 m away. The initial velocity makes an angle 26o with the horizontal. The target is hit. The acceleration of gravity is 9.8 m/s2 .
What is the magnitude of the initial velocity?
Answer in units of m/s
y = viy•t +0.5•ay•t2
vix = vi•cos(Theta)
vfy = viy + ay*t
I made a triangle with angle 26o, x=605, then solve for Ymax then got 265.214m. I think the next step is solving for time to get some kind of velocity of X or Y. Is 265m correct, what do I solve for next and how?
Any suggestions or advice welcome
