Question

a body of mass 25 kg has a momentum oh 0.40kg m/s .Find Kinetic Energy.

Answer 1

Hello friend!!!!!!!!

Thank you for asking questions????

So let's start,

Given:

Mass,m= 25kg

Momentum,p= 0.40 kg m/s

Kinetic energy = ?

For finding the kinetic energy velocity is essential...

So first we find the velocity...okk

We know that,

Momentum,p = m*v

V = P/m

V = 0.40/25

V = 0.016 m/s

Now we have calculated the velocity

So now we can easily find the kinetic energy,

Let's go,

We have the formula for finding the kinetic energy,

K.E = 1/2 mv^2

K.E = 1/2*25*(0.016)^2

K.E = 0.0032 J
