20 N force moving a box to 30 meters distance. How much work id done? if it takes 10 sec to do this work, how much power is used
dalvyx [7]

Answer:

Work done = 600 J

Power used = 60 W

Explanation:

Given:

Force acting on the box is, F=20\ N

Displacement of the box is, S=30\ m

Time taken for the work, t=10\ s

Now, we know that, work is said to be done by a force only when there is displacement caused by the force in its direction.

Here, the force acting on the box causes a displacement of 30 m in its direction. So, work done is equal to the product of force and displacement caused.

Therefore, work done on the box is given as:

Work=Force\times Displacement\\Work=F\times S\\Work=(20\ N)\times (30\ m)\\Work=600\ J

Therefore, the work done is 600 J.

Now, we know that, power is given as work done per unit time.

So, power used is given as:

Power=\frac{Work}{Time}\\\\Power=\frac{600\ J}{10\ s}\\\\Power=60\ W

Therefore, the power used is 60 W.
