Hope this helps!
Answer:
A. 36,000 W
Explanation:
= mass of the car = 900 kg
= Initial speed of the car = 20 m/s
= Final speed of the car = 0 m/s
= Work done by the brakes on the car
Magnitude of work done on the car by the brakes is same as the change in kinetic energy of the car.hence
= time taken by the car to come to stop = 5 s
= Average power produced by the car
Average power produced by the car is given as
The correct answer is conner because he has more than everyone else 4 is more than 3.5, 2.5, and 3
We have no idea WHAT the object is.
But if the 4.6 N is the ONLY force acting on it (including friction), then its mass is 282.2 grams.
