A suitcase of weight mg = 450 is being pulled by a small strap across a level floor. The coefficient of kinetic friction between the suitcase and the floor =0.640
a) Find the optimal angle of the strap above the horizontal. (The optimal angle minimizes the force necessary to pull the suitcase at constant speed.)
b) Calculate the minimum tension in the strap needed to pull the suitcase at constant speed?
My answer for a is 32.6 degrees...it's right... but I can't do b... My answer for the tension is 534N and I know it's wrong... Please help
