Solution 15.92 Step 1: FBD (a) - anyplace on the slope:, (b) At point B, (c) At point C At B N mg = m or solving for N 2 vB B 2 vB B N = mg + m (1) From Eq. 1 we see that N>0, thus, the skier does not lose contact with the ground and the limiting condition on acceleration at point B is aB = 2g At C: or 2 vB 2g B (2) N + mg = m or, solving for N 2 vC C N = mg m 2 vC C (3) Thus, at C it is possible for N to become negative and hence, for the skier can lose contact with the slope. The limiting condition on acceleration in this case is that aC = 2 vC g C (4) At this point we need to obtain relationships hA, between hB, hC and the velocities at points B and C. Since N does no work and mg is conservative we use conservation of energy between A and B and then between A and C. Thus, 1 TA + VA = TB + VB 0 1/2 mv2 (5) Using the ground as the datum for potential energy, then Eq. 5 gives us mghA = or 1 2 mv B + mghB 2 (7) (6) 2 v B = 2 g (hA hB ) Substitutin...
