An ball with a mass of M is launched off of a building of height h at an angle of Θ. The highest point in the ball's trajectory is Point P and Point Q is level with the launch height. Ignoring all effects of air resistance, what would the total mechanical energy be equal to at Point Q for the ball-Earth system?
a
1/2Mvoy2 + 1/2Mvox2
b
Mgh + 1/2Mvo2
c
Mgh
d
1/2Mvox2
