A .050-kg ball is shot at a velocity of 12 m/s by an upward-slanting cannon. At its maximun height, the kinetic energy of thew ball is 24J.
a) Tha max. height is?
b) the angel of the cannon to the horizontal is?
I really don't know where to start on this question. If someone can give me the equation I should used, I can go from there. I am thinking that I have to work backwards using the kinetic energy.
