Question

2 masses are connected by massless string over mas andfrictionless pulley. Mass m1 is moving downward withacceleration =2m/s squared Mass 1 =50 kg. M2 is on anincline plane connected to m1. It is a 30 degree inclinerelative to horizontal. M2 is on incline M1 is hanging frompulley. Calculate tension in string assuming no friction Calculate ms assuming no friction between m2 and plane Assuming coefficient of kinetic friction is 0.5 between m2 andplane calculate ms 2 masses are connected by massless string over mas andfrictionless pulley.

Explanation / Answer

   m1 = 1.50 kg    W1 = (1.50 kg) (9.80 m /s2)          = 14.7N    m2 = ...... kg    W1 = ....... N    k = 0.5    = 30o    if a is the acceleration we can write    Fy = W2 - T= (m2) (a) ...........(1)    n = (W2) cos 30o       = ........N    f = (k) (n)      = (0.350) (n)    Fx = T - f - (W2)(sin30o)           =(m2) a ...........(2)    solve for the result
