Explanation:
The kinetic energy of a body is the energy possessed by the body due to its motion.
Mathematically, it is given by the equation:
where
m is the mass of the body
v is the speed of the body
For the skydiver in this problem, at the istant mentioned we have:
m = 90 kg is the mass of the skydiver
v = 8 m/s is his speed
Therefore, the kinetic energy is
