Date:
A body has a mass m and velocity v , if the mass is increased to 4 times and velocity is decreased to 2 times calculate the ratio of kinetic energy

Explanation:

Mass = m

Velocity = v

If Mass is increased 4 times = 4m

New velocity = 2v

Kinetic Energy

[tex] \frac{1}{2}m {v}^{2} [/tex]

So it will be 1/2 × 4m × 2v × 2v

[tex]8m {v}^{2} [/tex]

so Kinetic Energy will increase 4 times
