Question

A man weighing 60 kg runs with the speed of 5 m/s. Find the kinetic energy possessed by him...​

Answer 1

Answer:

hi

Explanation:

Given, mass of the man, m=60kg

Kinetic energy of the man, E  

k

​  

=750J

If v is the velocity of the man, then

Answer 2

⭐⭐⭐Answer⭐⭐⭐

✪ Formula Required ✪

Kinetic energy = $\frac{1}{2}$ x $m$ x $v^{2}$

Here m is the mass

v is the velocity

✪ Process ✪

Given that mass is 60 Kg and velocity is 5 m/s.

Substituting the values in the formula, we get:

Kinetic energy = $\frac{1}{2}$ x $60$ x $5^{2}$

                          = $30$ x $25$

✪ Hence ✪

Your answer is:

$\huge\boxed{750 J}$
