Answer:
v = 10.65 m/s
Explanation:
Given that,
Mass of a jogger, m = 73 kg
The kinetic energy of the continent is, E = 4140 J (say)
ATQ,
A jogger will have same kinetic energy as that of the continent. So, the kinetic energy of the jogger is 4140 J.
The formula for kinetic energy is given by :
[tex]K=\dfrac{1}{2}mv^2[/tex]
v is the speed of the jogger
[tex]v=\sqrt{\dfrac{2k}{m}} \\\\v=\sqrt{\dfrac{2\times 4140}{73}} \\\\v=10.65\ m/s[/tex]
So, the speed of the jogger is 10.65 m/s.
