Question

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

Answer 1

u know to calculate friction force?

Answer 2

no

Answer 3

at least the formula?

Answer 4

no sorry

Answer 5

@baru

Answer 6

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

Answer 7

so i would multiply 12 and 0.12

Answer 8

where did 12 come from?

Answer 9

from μs

Answer 10

weight of the sled? how much is that? in Newtons

Answer 11

490.332501432

Answer 12

@baru

Answer 13

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 \(\times \mu_k \))
