A 1130 kg car is initially at rest when it accelerates up a 21 m high hill. When it reaches the top of the hill it is traveling at 18 m/s. If it takes 6.5 s to reach the top of the hill, what was the average power of the car?
Homework Equations
W = Fd
P = w/t
The Attempt at a Solution
My answer was 45887.36 watts. The methodology used can be seen in the attached picture.
Power is the rate at which work is done or energy is transferred. It is measured in watts (W) or horsepower (hp).
Power and acceleration are related through the formula P = Fv, where P is power, F is force, and v is velocity. This means that the more power a car has, the faster it can accelerate.
Average power is the average rate at which work is done or energy is transferred over a certain period of time. It is calculated by dividing the total work or energy by the time it took to do it.
To calculate average power for a car accelerating up a hill, you would need to know the force applied by the car's engine, the velocity of the car, and the time it took for the car to reach a certain point on the hill. Then, you can use the formula P = Fv to calculate the average power.
The average power of a car accelerating up a hill can be affected by various factors such as the weight of the car, the incline of the hill, the engine's horsepower, and the car's aerodynamics. Other external factors like wind resistance and road conditions can also impact the average power of a car.
