Question

How much power does an Ox pulling a plow 20 m cross a field, exerting 120J of work over a period of 15 s?​

Answer 1

8W

Step-by-step explanation:

Given parameters:

Distance covered = 20m

Work done = 120J

Time = 15s

Unknown:

How much power does the Ox exerts = ?

Solution:

Power is the rate at which work is being done

Power =
`(Work done )/(time)`

Power exerted by ox =
`(120)/(15)` = 8W
