Question

A truck driver pushes the acceleration to peddle and increase its speed from v to 2v on the level Road. The mass of the Truck is M.
Work done by the acceleration peddle? A.1.5Mv2
B.PE of the truck becomes four times of the initial Potential energy
C.Mv2 ​

Answer 1

Answer:

A.1.5Mv2

Explanation:

Since it is running on level road. PE does not change

Initial Kinetic Energy = 1/2 Mv²

Final Kinetic Energy= 2Mv²

Work done by the acceleration peddle= Final KE - Initial KE= 1.5Mv²
