Okay another projectile motion question. I'm a bit confused by how to work this out.
---
A cannon will a muzzle speed of 1000m/s is used to start an avalanche on a mountain slope. The target is 2000m from the cannon horizontally and 800m above the cannon. At what angle, above the horizontal, should the cannon be fired?
---
I was thinking that i would have to work out the angle to which the cannon should fire if the target was at its vertical level, 2000m away horizontally. Then somehow (i don't know how), using this angle in a further equation, that i don't know of, to include the difference in height?
Can anyone help?
Regards.
