Find the Tension in the rope ....( really simple :D) 1. The problem statement, all variables and given/known data A block pulled by a string is moving on a horizontal plane with a constant speed, it weighs 25.0 N and its coefficient of kinetic friction is 0.35 . Find the tension in the rope ? 2. Relevant equations Fx = t - Fk T = Fk = μk * N = μk *mg 3. The attempt at a solution My answer results 85.84 N ... which is completely off the textbook answer 8.75 which can be yield by μk * m ..... I dont understand why does it eliminate the 'g' out of the equation???
