a car performs 40,000 j of work in 5 sec. what is the power of the car. what is the horsepower?
To find the power of the car, we can use the formula:
Power = Work / Time
Given that the car performs 40,000 joules of work in 5 seconds, we can substitute these values into the formula:
Power = 40,000 joules / 5 seconds
Now, let's calculate the power:
Power = 8,000 watts
To convert the power from watts to horsepower, we can use the conversion factor: 1 horsepower = 746 watts.
Horsepower = Power / 746
Now, let's calculate the horsepower:
Horsepower = 8,000 watts / 746
Horsepower ≈ 10.72
Therefore, the power of the car is 8,000 watts and it is approximately equal to 10.72 horsepower.
