8.1

A 17.0-kg cannonball is fired from a cannon with muzzle speed of 1 100 m/s at an angle of 35.0° 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.

(a) Use the isolated system model to find the maximum height reached by each ball.

hfirst ball = m
hsecond ball = m


(b) Use the isolated system model to find the total mechanical energy of the ball–Earth system at the maximum height for each ball.

Efirst ball = J
Esecond ball = J
