A 18.0-kg cannonball is fired from a cannon with muzzle speed of 1 050 m/s at an angle of 32.0° with the horizontal. A second ball is fired with the same initial speed at an angle of 90.0°. Let y = 0 at the cannon. %3D (a) Use the isolated system model to find the maximum height reached by each ball. nfirst ball m second ball (b) Use the isolated system model to find the total mechanical energy of the ball-Earth system at the maximum height for each ball.
