How much force is required to start moving a 2 kg block of steel on dry...
How much force is required to start moving a 2 kg block of steel on dry steel if there is a 5 N force opposing you? How much is required to keep it from slowing down assuming the opposition force remains? (For steel on dry steel, μs = 0.8 and μk = 0.5.)
Homework Answers
Here i have attached a scanned sheet for the solution.
For the first part we will have to use the value of statics friction coefficient and for the other part we will have to use kinetic friction coefficient.
Since in both of the cases 5 N force is in opposition so we will have to add this 5 N in answer. See how:
