marco pushes a stalled car 20 meters with a constant force of 500N in 50 seconds. Calculate the average power marco required to move the car.
500 * 20 / 50 in Joules
To calculate the average power required by Marco to move the car, you need to use the formula:
Average Power = Work Done / Time
First, let's determine the work done by Marco in pushing the car. Work is calculated using the formula:
Work = Force × Distance
Given that the force applied by Marco is 500 N and the distance moved is 20 meters:
Work = 500 N × 20 m
Work = 10000 N·m (Newton meters or Joules)
Next, we need to determine the time it took for Marco to perform this work. In this scenario, the time given is 50 seconds.
Now we can substitute the values into the formula for average power:
Average Power = Work Done / Time
Average Power = 10000 N·m / 50 s
Average Power = 200 Watts (W)
Therefore, Marco required an average power of 200 Watts to move the car.
