Solving the Problem: Work, Power & Friction

[soulja101]

I can't get this question. I've tried everyway i could think but i still can't get it.

A force of 5.0N moves a 6.0kg object along a rough floor at 2.5m/s

11. How much work is done in 25s by the force.
12.what power is being developed.
13. what force of friction is acting on the object(magnitude only).

What have you tried? Pick your best way. Let us see it.

I ve tried these formulas force*distance and m*g*h* they still don't work

 

[Dorothy Weglend]

You are on the right track with Force * distance. More details would be nice. What, exactly, did you use for Force and distance? How did you get it?

wat i used

i used 5.0N as the force and i got stuck there becuase i couldn't find the distance.

Your problem says that the speed is a constant 2.5 m/s. And then it asks how much work is done in 25 s...
