Question

1.The brakes on a hospital gurney are stuck and you can't unlock them. It requires you 1200Nto drag it (with the patient on it) across the floor. The patient has a mass of 102 kg andgurney has a mass of 36.2 kg. (a)Draw a labelled diagram including all forces, with a sign convention and list all knowns etc (b) Determine the coefficient of static friction (c)The brakes finally become unstuck, and the wheels roll free. If the coefficient of rolling friction is 0.085, determine the force required to continue pushing it at constant velocity. (d) If you stop pushing, how far will it take to come to rest
