5 Timmy pulls with a force of 35 N on the massless rope which belongs to the pulley arrangement shown. Pulley wheels A, B, and C are fixed to the wall and don't move. The pulley system is frictionless. The cart's rolling friction is not negligible. Timmy's feet do not slide on the cart surface. A) What is Timmy's acceleration? B) Calculate the friction force on Timmy's shoes. What type of friction is this? A M7 = 28 kg mc = 15 kg Hy = 0.02 B mc

Learning Goal: In 1687, Isaac Newton presented three basic laws that describe the motion of a particle: • First law: A particle originally at rest, or moving in a straight line with a constant velocity, will remain in this state provided that the particle is not subjected to an unbalanced force. Second law: A particle acted upon by an unbalanced force, F experiences an acceleration, a, that has the same direction as the force and a magnitude that is directly proportional to the force.

Solve with paper and pencil, scan your solution, and submit online. 15° A person pulls themself up a 0 = 15° incline by the method shown. The combined mass of the person and cart is m = 100 kg, and starting from rest they pull the rope with a force of P = 250 N. Neglect all friction and the mass of the pulleys and wheels. (a) Find the acceleration of the person and cart. (b) How fast is it moving after it has traveled 1 m ?
