1. Homework Statement If a certain cannon can shoot a projectile a distance of 275m when it is aimed at 66.0 degrees above the horizontal, what is the maximum range the cannon could achieve with the same projectile, and at what angle should it be aimed to do this? 2. Homework Equations...

My answer to part a) Ok, I used the kinematical equation Vy^2 = Voy^2 + 2ay(y-yo) to find the velocity of the package relative to the ground and I got 12.9 m/s downward (or -12.9m/s). I plugged this value into my equation as Vp/g. I know that the velocity of the helicopter relative to the...

Thank you so much! I will try my best to solve the problem and let you know what I come up with

Yes I am, but I don't know what equation to apply to this problem to solve it. The equation I gave was listed in my textbook as a way to solve relative velocity problems: velocity of the package relative to the helicopter = (velocity of the package relative to the ground) + (velocity of the...

1. Homework Statement A helicopter 8.50 m above the ground and descending at 3.50 m/s drops a package from rest (relative to the helicopter). Just as it hits the ground, find a) the velocity of the package relative to the helicopter and b) the velocity of the helicopter relative to the...
