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 78kg 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
