Question

Block B, of mass m, = 0.5kg, rests on block A, with mass m, =1.5 kg, which in turn is on a
horizontal table top (as shown in figure). The coefficient of kinetic friction between block A and the
table top is y, = 0.4 and the coefficient of static friction between two block A and block B is
Hs = 0.6. A light string attached to block A passes over a frictionless, massless pulley and block C is
suspended from the other end of the string. What is the largest mass me (in kg) that block C can
have so that blocks A and B still slide together when the system is released from rest? (g = 10 m/s2)​

Answer 1

aForests are considered 'biodiversity hot spots' because large number of life forms (such as bacteria, fungi, fern, nematodes, insects, birds, reptiles, mammals, gymnosperms and angiosperms) are found there. These are the regions with large biodiversity of endangered species, many of them being highly endemic
