The kinetic energy (KE) of an object can be calculated using the formula:

KE = (1/2) * mass * velocity^2

In this case, the skater has a mass of 50 kg and is moving at a speed of 5 m/s. Let's substitute these values into the formula:

KE = (1/2) * 50 kg * (5 m/s)^2

Calculating this expression:

KE = 0.5 * 50 kg * (25 m^2/s^2)

KE = 625 Joules

Therefore, the kinetic energy of the skater is 625 Joules.
