Question

when the momentum of a body increases by 100% its kinetic energy increases by

Answer 1

MOMENTUM=MASS*VELOCITY........MASS IS CONSTANT..........WHEN MOMENTUM IS INCREASED BY 100% IT MEANS THE VELOCITY OF THE BODY IS INCREASED BY 100% OR THE FINAL VELOCITY NOW TWO TIMES THE INITIAL VELOCITY.AND KINETIC ENERGY =1/2*(MASS* VELOCITY^2).HENCE THE KINETIC ENERGY IS INCREASED BY 4 TIMES THE INITIAL VELOCITY.
