A 2.00kg projectile is launched from the earth's surface with an initial velocity of 38.0 m/s at an angle of 45 degrees with respect to the horizon. The projectile lands on the ground some distance away.
a) What is the work done by gravity on the projectile?
b) how would this change if air resistance were accounted for?
