3. (40 points)/Dr. Quincy sits in the coroner's office thinking of how much better life would have been had his major been physics. So he decides to do an experiment to find the coefficients of friction between a severed hand and a stainless steel gurney. Dr. Quincy finds that he must raise one end of the 2-m long gurney I m before the severed hand begins to slide. And it takes 1.5 s for the hand to reach the bottom. (a) Begin by drawing a free body diagram representing all the forces acting on the hand. Im 7 (b) Use Newton's Second Law to find the coefficient of static friction between the hand and gurney. (e) What acceleration does the hand experience on its way down the gurney? (d) Use Newton's Second Law to find the coefficient of kinetic friction / between the hand and gurney
