Sure, to find the speed of the sprinter, we can use the formula for kinetic energy, which is KE = 1/2 * m * v^2, where KE is kinetic energy, m is mass, and v is velocity (or speed in this case).

Given that the kinetic energy (KE) is 4000 J and the mass (m) is 80 kg, we can rearrange the formula to solve for v:

v^2 = 2 * KE / m

Substituting the given values:

v^2 = 2 * 4000 J / 80 kg = 100 m^2/s^2

To find v, we take the square root of both sides:

v = sqrt(100 m^2/s^2) = 10 m/s

So, the sprinter's speed is 10 m/s.
