Suppose a skydiver (mass = 75kg) is falling toward the earth. when the skydiver is 100m above the earth he is moving 60m/s. at this point calculate the gravational potential energy kinetic energy

From the question,
The mass of the skydiver,



The height from the Earth at which the skydiver is before falling,



Velocity, V of the skydiver



Let us take acceleration due to gravity to be ;


The mass of the skydiver, m=75kg

The height from the Earth at which the skydiver is before falling, h=100m

Velocity, V of the skydiver =60m/s

Potential energy, P.E can be calculated from the relation;
P.E = mgh


P.E =75000 J

Therefore, the gravitational potential energy of the skydiver is 75000 J

Kinetic energy,K.E




=135000 J

Hence the kinetic energy of the Skydiver is 135000 J
