Question

If the speed of an object is doubled then it's
Option a kinetic energy is doubled
Option b kinetic energy is raised to 4 times
Option c potential energy is doubled
Option d potential energy becomes 4 times of its initial value

Answer 1

Answer:

Option b

Explanation:

Kinetic energy =1/2mv×v

K.E proportional to v×v

so that ,

K.E increased by 4

Answer 2

Answer:

Option b is correct

kinetic energy is raised to 4 times
