|| BIO Injuries to the spinal column. In treating spinal injuries, it is often necessary to provide some tension along the spinal column to stretch the backbone. One device for doing this is the Stryker frame, illustrated in part (a) of Figure 5.56 . A weight W is attached to the patient (sometimes around a neck collar, as shown in part (b) of the figure), and friction between the person’s body and the bed prevents sliding. (a) If the coefficient of static friction between a 78.5 kg patient's body and the bed is 0.75, what is the maximum traction force along the spinal column that W can provide without causing the patient to slide? (b) Under the conditions of maximum traction, what is the tension in each cable attached to the neck collar? (a) (b) Figure 5.56 Problem 37.

World-class sprinters can accelerate out of starting blocks with an acceleration that is nearly horizontal and has magnitude 15m/s². How much horizontal force must a 55 kg sprinter exert on the starting blocks during a start to produce this acceleration?
I contestant in a Winter games event polls a 59.0 KG block of ice across a frozen Lake with a rope over shoulder the coefficient of static friction 0.1 and the coefficient of kinetic friction is 0.03 calculate the minimum force F he must expert to get the black moving? What is its acceleration once it starts to move if that force is maintained?
As part of an attempt to combine physics and biology in the sameclass, an instructor asks students to weigh a 5.2-kg salmon byhanging it from a fish scale attached to the ceiling of an elevator.What is the apparent weight of the salmon, W>a, if the elevator (a)is at rest, (b) moves with an upward acceleration of 3.5 m>s2, or (c)moves with a downward acceleration of 2.3 m>s2?
