f momentum is increased by 20% then K. E increase by:

Explanation

Option A is correct according to the following calculations. The increase in kinetic energy is 44%. The momentum of a body is given by the product of its mass and velocity. The kinetic energy of a body is given by the product of half of its mass and the square of its velocity. If the momentum is increased by 20%, then the mass or velocity of the body must increase by 10%. The kinetic energy of the body will increase by 44%. The following equation shows the relationship between momentum, mass, velocity, and kinetic energy: Momentum = Mass * Velocity Kinetic Energy = 1/2 * Mass * Velocity^2 Let's assume that the initial momentum of the body is 100 units. The mass and velocity of the body will increase by 10%, so the final momentum of the body will be 120 units. The final kinetic energy of the body will be 144 units, which is an increase of 44% from the initial kinetic energy of 100 units. Therefore, the increase in kinetic energy is 44%.
