PhysicsEasysingle choice

The speed $v$ reached by a car of mass $m$ driven with constant power $P$ is given by

Options:

Answer:

Solution:

$P = F v$

or $P = (m v \frac{d v}{d x}) v$

or $\int_{0}^{v} v^{2} d v = \int_{0}^{x} \frac{P}{m} d x$

$\frac{v^{3}}{3} = \frac{P x}{m}$ or $v = {(\frac{3 P x}{m})}^{1 / 3}$
