Homework Statement
A canon ball is fired from a canon upwards at an angle above the horizontal.
a. Sketch a graph showing the height of this canon ball over time if it was fired at 30°, 45° and 60° above the horizontal.
b. Sketch showing the acceleration of the canon ball over time if it was fired at 30°, 45° and 60° above the horizontal.
c. At what point in the flight of the canon ball is the velocity at a minimum?
Homework Equations
h*sin(angle) = hy
h*cos(angle) = hx
The Attempt at a Solution
I have sketched 3 triangles but how do I work out the components with just an angle? Or is there another way of doing this?
