The velocity of a bus, moving on a smooth road, is increased from 8 m/s to 32 m/s in 120s. During this process, the potential energy of the bus

হানি নাটস

As potential energy, P=mghP=mgh

Since, there is no vertical displacement so, h=0h=0.

Hence, potential energy changeP=mgh=0P=mgh=0

The moving bus has only change in its Kinetic energy.
