A mass M= 6.2 kg on a plane inclined at angle 33° is connected by a cord parallel to the plane then over a frictionless, massless pulley to a suspended rock of mass R. The friction coefficient, µ=.25 between the mass and the plane.
(See pictures in attachment File #1.)
Find the mass of the rock for the following situations:
a. The rock is accelerating downward with acceleration a= 2.27 nt/kg.
b. The rock is accelerating upward with acceleration a= 1.17 nt/kg.
c. The rock is moving upward with constant speed.
d. The rock is moving downward with constant speed.
