Question

if the kinetic energy of a body is double of its initial kinetic energy then the momentum of the body will be​

Answer 1

if momentum of a body is doubled without change in the mass of the body then it means the velocity of the body has increased by 2
now for the kinetic energy of the same body it will increase by 4 , since it is half MV square

so if v is doubled in case of momentum then it increases by 4 in case of Kinetic energy of the body
If we go for the opposite case if velocity increases by 2 in case of Kinetic energy then in case of momentum it will increase by √2

since , momentum is directly proportional to Kinetic energy

Answer 2

Answer:

momentum becomes 1.4142 times

Explanation:

p=$\sqrt{kinetic energy}$

p=$\sqrt{2}$

p=1.4142 times
