The speed with which runner is running is 7.07m/s
Explanation:
Given:
Mass, m = 60kg
Kinetic energy, KE = 1500J
Velocity, v = ?
We know,
Kinetic energy = [tex]\frac{1}{2} mv^2[/tex]
On substituting the value we get,
[tex]1500 = \frac{1}{2} X 60 X v^2\\\\v^2 = 50\\\\v = 7.07 m/s[/tex]
Therefore, the speed with which runner is running is 7.07m/s
