In the system shown, a 150 N collar-pulley assembly slides on a horizontal shaft with coefficient of kinetic friction k = 0.10 between the collar and the shaft, and is acted upon by a force P with a magnitude - of P = (250 ) N at an angle 0 = (30 ) as shown. Knowing that the assembly is initially at rest, what is the velocity of collar B after 3 seconds? what is the time when the velocity of collar B reaches to 3 m/s? Also, at this instant, find the tensile force in the cord and the velocity of block A. P e W = 150 N B C C A W = = (100 .) N
