    Friction and accelerarion....please check my work.

    a horizontal force of 200 Newtons is applied to a 55 kg cart across a 10 meter surface. If the cart accelerates at 2 meters/second squared, then what is the work done by the force of friction as it acts to retard the motion of the cart ??

    Work= FX
    work= maX

    55 kg x 2 x 10 = 1100 - 200 N = 900 Joules ??

    is this correct ?

    Re: Friction and accelerarion....please check my work.

    If there would have been no friction, what will be the acceleration of the cart when 200 N force is applied?
    What is the actual acceleration?
    What is the retardation due to frictional force?
