Homework Statement
A coastal defence cannon fires a shell horizontally from the top of a 50.0m high cliff directed out to sea with a velocity of 60.0m/s.
Determine the range of the shell's trajectory.
Homework Equations
delta x = ut (horizontally)
delta y = ut + 1/2 at^2
The Attempt at a Solution
working vertically
50 = 0t + (1/2 * 9.8 * t^2)
t = 3.2
working horizontally
delta x = ut
delta x = 60 * 3.2
delta x = 192
therefore the range is 192m
I'm not too great with physics although really willing to learn and really interested in it :)
Can someone just confirm I'm right or put me on the right track
