These tasks: m (athlete’s weight) = 50 kg; V (speed of movement (running)) = 6 m / s.
To calculate the kinetic energy of a given athlete, we will use the formula: Ek = m * V ^ 2/2.
Let’s perform the calculation: Ek = 50 * 6 ^ 2/2 = 900 J.
Answer: When moving at a speed of 6 m / s, the athlete will have a kinetic energy of 900 J.
