Hi, I am currently studying advanced diploma in marine engineering and I was told this was a very helpful site i can relate to.

A cannon fires a projectile at a range of 3000m with an initial angle of 30 degrees to the horizontal. Find:

a)the actual velocity at which the projectile is fired?
b)the maximum height reached?
c)the time taken to reach this range?
