The speed with which runner is running is 7.07m/s

Step-by-step explanation:

Given:

Mass, m = 60kg

Kinetic energy, KE = 1500J

Velocity, v = ?

We know,

Kinetic energy =
(1)/(2) mv^2

On substituting the value we get,

$1500 = (1)/(2) X 60 X v^2\\\\v^2 = 50\\\\v = 7.07 m/s$

Therefore, the speed with which runner is running is 7.07m/s
