Question

A jogger (of mass 73 kg) has the same kinetic energy as that of the continent. What would his speed be

Answer 1

v = 10.65 m/s

Step-by-step 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 :

`K=(1)/(2)mv^2`

v is the speed of the jogger

`v=\sqrt{(2k)/(m)} \\\\v=\sqrt{(2* 4140)/(73)} \\\\v=10.65\ m/s`

So, the speed of the jogger is 10.65 m/s.
