This problem involves both projectile motion and energy conservation. Whenever the mass of the object is given, we can always use energy to solve energy conservation to solve projectile motion problems.

A 20.0-kg cannonball is fired from a cannon with muzzle speed of 1 000 m/s at an angle of 37.08 with the horizontal. A second ball is fired at an angle of 90.08. Use the isolated system model to find

(a) the maximum height reached by each ball and

(b) the total mechanical energy of the ball–Earth system at the maximum height for each ball. Let y =0 at the cannon.
