You shoot a cannon with initial velocity 62.3 m/s at an angle 67 degrees with respect to the level field on which the cannon sits. Use gravity = 9.80 m/s2.
a) How far does this cannonball go on level ground?
b) You then fire a second shot at an angle of 57 degrees. With what speed must the second cannonball be launched in order for it to reach the same peak height as the first ball?
