Notes for 10/16 Coefficient of Friction
Solutions to example problems from 10/30
Ex 1: a = .44 m/s/s, coefficient of friction is 0.045
Ex 2: T = 76.6 N, a = 3.9 m/s/s
Ex 3: Coefficient of friction is .31 (Ff = 14.31 N, Fn = 46.04)
Ex 4: Accelerating up at 2.1 m/s/s means scale reads 655 N,
Constant velocity - scale reads 539 N
Accelerating down at 1.4 m/s/s - scale reads 462 N
