One day George was experimenting with friction and attempting to pull Al across the surface of a floor. George applies a pulling force of 60 N and Al weighs 103 N.
a. What is the reaction force?
b. Assuming the coefficient of static friction is 0.65, what is the friction force?
c. Does Al move? Why or why not?
