If momentum of an object is increased by 10%then it's ke will increase by |
|
Answer» Answer: ke will increase by 21% Explanation: momentum is product of MASS and VELOCITY =mv Kinetic energy = 1/2 mv^2 = 1/2 momentum^2/m assume mass is constant now ke = a.momentum^2 (.5/m taken as CONTANT a) now momentum increased as 1.1 mv ke will increase as square of 1.1 i.e. ke will increase as 1.21ke that is by 21% |
