Power and Work

  1. Nov 12, 2006 #1
    I cant get this question. ive tried everyway i could think but i still cant 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 dont work

    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 couldnt 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...
