Question
Two blocks are connected by L=h1+L1+ h2+L2+e; (h1=6m, L1=2m, h1=2m, L1=12m, e=1m) long rope that passes through a pulley. The rope and the pulley have negligible mass and no friction. Block A has a mass mA= 1.0 Kg. and is hanging vertically, while block B has a mass mB= 2.0 Kg. rests over a frictionless surface. The path is without friction until it reaches the section of length L2. The coefficient of kinetic friction is µk=0.7 in section L2. If the blocks are released from rest:
a.) What are the speeds of the blocks at points (1) and (2)
b.) Does the block B reach point (3) at the end of section L2? If so what is the speed there? If not, how far through the section of friction does it travel?
L hi L2 h2 L1Explanation / Answer
Mass of block B is greater then mass A so they will never move on the track so answer for all parts is zero.
