Homework Statement
A launcher fires a ball that weighs 30kg straight up to a height of 300m. What is the maximum range of the ball could be fired at?
Homework Equations
V^2 = V^2-2(a)(d)
R = ( V02 Sin2θ ) / g
The Attempt at a Solution
To find the maximum range i know that it has to be fired at a 45° angle.
It is in our energy and momentum etc. unit, practice so I am guessing equations relevant to that is what i must use.
I used this equation to find the Velocity when fired straight up. Which i got 76.68 m/s. Which if i drew a triangle to show the projectory, would be my height. I then used 76.68SIN(45°) to get 54.22 m/s. Which is my x & y velocity. Then i used the range formula to get 300 m.
Is anything wrong with my work, shouldn't it be a different answer than 300m.
