A 2.00 kg remote controlled car is equipped with a single electric motor that provides the car with the power necessary for it to accelerate.
a. The maximum power rating of the electric motor is 168 Watts. Using the motor at this maximum rated power, how long will it take to accelerate a 2.00 kg car from 5.00 m/s to 14.5 m/s if we neglect all frictional losses?
b. Calculate the average acceleration of the car during this period.
c. Calculate how far the car moves during this period. Start from the point where the car was moving at the initial velocity of 5.0 m/s and end at the point where the car has achieved the final velocity of 14.5 m/s.

Consider a Porsche 911 sports car with a mass of 1900 kg. The air drag force at highway speeds can be approximately calculated as: F_drag = 1/2 C p Av^2 where p = 1.2 kg/m^3 is the density of air, A is the front area of the car, C is the drag coefficient and v is the velocity. For the Porsche 911, we can take A - 2.3 m^2 and C = 0.28. What is the power necessary to overcome...
