Question

A car is accelerated on a level road and attains a velocity 4 times of its initial velocity . In this process the potential energy of the car

Answer 1

Potential Energy -

U_{f}-U_{i}= \int_{r_{i}}^{r_{f}}\vec{f}\cdot \vec{ds}

- wherein

U_{f}-final\: potential\: energy

U_{i}-initial \: potential\: energy

f-force

ds-small \: displacement

r_{i}-initial \: position

r_{f}-final\: position

Remains Same (No Change) because potential energy is independent of velocity
