Chapter 8, Problem 8.90(choose chapter or problem)
The small mass m sliding without friction along the loopedtrack shown in Fig. 8-44 is to remain on the track at all times,even at the very top of the loop of radius r. (a) In terms of thegiven quantities, determine the minimum release height h.Next, if the actual release height is 2h, calculate the normalforce exerted (b) by the track at the bottom of the loop,(c) by the track at the top of the loop, and (d) by the trackafter the block exits the loop onto the flat section.FIGURE 8-44 90.
