What is the power of a 900 n force applied over a distance of 40 m for 45 sec?
work = force * distance in direction of force
power = work per unit time
so
900 * 40 /45
in Newton meters/second which is JOULES
Power = work/time = 900N*40m/45s
power is in Watts, by the way. Work is Joules.
Whoops, sorry.
Watts.
Thank you for catching that
To calculate power, one must use the formula: Power = Work / Time.
First, we need to calculate the work done by the force. Work is given by the formula: Work = Force * Distance.
Given that the force is 900 N and the distance is 40 m, we can calculate the work done as follows:
Work = 900 N * 40 m
Next, we need to calculate the time in seconds. Given that the time is 45 sec, we can use the given value directly.
Now, we can substitute the values into the power formula:
Power = (900 N * 40 m) / 45 sec
Simplifying further:
Power = (36000 Nm) / 45 sec
Finally, we can calculate the power:
Power = 800 watts.
Therefore, the power of a 900 N force applied over a distance of 40 m for 45 seconds is 800 watts.
