# Check my physics

posted by .

Would you mind checking one of my problems from my physics study guide? I know the answer and just want to make sure I am using the right formula. :)

A 78-kg skydiver has a speed of 62 m/s at an altitude of 870 m above the ground.
a. Determine the kinetic energy possessed by the skydiver. (149916 J)

Formula: K.E=1/2mv2
b. Determine the potential energy possessed by the skydiver. (665028 J)

Formula: P.E=mgh
c. Determine the total mechanical energy possessed by the skydiver. (814944 J)

Formula: M.E=K.E + P.E
