A mother brings her 8-year-old son to the clinic. Three days earlier he and another child had been “sword fighting” with wooden swords. The boy received a sharp blow to his right lower extremity, and since then his foot has “dragged” when he walks. Physical examination shows that he can raise up on his toes, but cannot walk on his heels. Further testing shows that he cannot dorsiflex his right foot. Sensation is intact on the foot, except for numbness of the web space between the first and second digits. At what spinal level are the cell bodies that give rise to the motor axons (GSE) that were damaged?

You will use this problem for Questions 13-15. Read carefully! A bike is suspended on a rack so that its wheels spin freely and the brakes can be tested. The mass of each wheel is 1.36 kg, and the radius of each wheel is 0.35 m.   Q13:  If one of the wheels is spinning at 13.5 rad/s, and it slows to 3.1 rad/s when the brake is applied for 2.9 seconds, find the angular acceleration of the wheel. Q14:  Assume that all of the mass of the wheel is concentrated on its outer rim, find the magnitude of the torque exerted by the brake pads on the wheel.  (I = mr2)  Q15: BONUS  Find the magnitude of the friction force exerted by the brake pad on the rim.
