Question

you push a box across the floor with a force of 30n you it 15 meters in 8 seconds. how much work did you do how much power did you see

Answer 1

20m/s newtons per second

Answer 2

Answer : W = 450 J and P = 56.25 Watts

Explanation :

It is given that,

Force, F = 30 N

Distance, d = 15 m

Time, t = 8 sec

The work done is given as :

W = F.d

`W=30\ N* 15\ m`

`W = 450\ J`

So, the work done to push a box across the floor is 450 N.

Mechanical power is defined as,

`P=(Work)/(time)`

`P=(450\ J)/(8\ s)`

P = 56.25 Watt

The power is 56.25 Watts.

Hence, this is the required solution.
