A 50.0 kg sled is placed on ice where μs=0.12 and μk=0.08. A child attaches a rope to the sled and slowly increases the tension in the rope. Calculate the force of friction acting on the sled when the tension is the following values: a. 25N b. 50 N c. 75 N d. 100 N

friction force = \(weight \times \mu\)

so i would multiply 12 and 0.12

where did 12 come from?

accurate to 9 decimal places?wow!! how did you get that?? calculate friction force using \(\mu_s\) first and then with\(\mu _k\) if tension applied is greater than friction force calculated with \(\mu_s\) then, firction force = (weight \(\times \mu_k \))
