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 ?

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?

Yes, your calculation is correct. The work done by the force of friction is 900 Joules. This means that 900 Joules of energy is converted into heat due to the friction between the cart and the surface. This is an important concept in physics as it helps us understand how forces and motion interact in real-world situations. Keep up the good work!
