A 400 kg glider is traveling at 16 m/s at a height of 200 m above the ground. Calculate the total energy of the glider if the glider drops to a height of 100 m.
Assume that there are no energy losses due to air friction and that the acceleration due to gravity at the Earth’s surface = 10 m/s2.

A.
800 kJ
B.
400 kJ
C.
450 kJ
D.
850 kJ
