A1430 kg car speeds up from 7.50 m/s to 11.0 m/s in 9.30 s. ignoring friction, how much power did that require? (unit=w)

4980 W

Explanation:

Power = change in energy / time

P = ΔKE / t

P = (½ mv₂² − ½ mv₁²) / t

P = ½ m (v₂² − v₁²) / t

P = ½ (1430 kg) ((11.0 m/s)² − (7.50 m/s)²) / (9.30 s)

P = 4980 W

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
