A cannonball is fired from a canon at an angle of 30 degrees to the horizontal.The cannonball's initial velocity is 40 m/s.
a) How far will the cannonball go before it hits the ground?
b) What is the greatest height the cannonball will attain?
c) How long will the cannonball be in flight before it hits the ground?
d) Would the cannonball travel farther if the angle was increased to 50 degrees?
