You expend 1000 w of power moving a piano 10 meters in 5 seconds. how much force do you exert

a. 50 n

b. 5 n

c.250 n

d. 500 n

Force, F = 500 N

Explanation:

Given that,

Power expanded, P = 1000 W

Distance moved by piano, d = 10 m

Time taken, t = 5 s

To find,

The force exerted by the person

Solution,

The rate at which the work is being done is called power delivered. Its formula is given by:

W is the work done, W = F × d

On rearranging the above formula to find F as :

F = 500 N

Therefore, the force exerted on the person is 500 N. Hence, this is the required solution.
