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

So it will be 1/2 × 4m × 2v × 2v

so Kinetic Energy will increase 4 times

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

unlike poles attract
