In the figure below, assume that the pulleys are massless andfrictionless.
The masses of the blocks are Ma=3.00 kg, Mb=6.00 kg, Mc=2.00 kg,and there is friction between the horizontal plane and Mb, (μkâ 0).Mb is observed to travel at a constant velocity.
(a) Answer Choices:G-Greater Than, L-Less Than, E-Equal To,T-True, F-False
(i) Ty is .... Tx
(ii) The magnitude of the total force on Mb is .... 0
(iii) Tz is .... Ty
(iv) Mb is moving to the right
(v) Ma accelerates downward
(vi) Mc*g is .... Tz.
(b)Calculate the coefficient of kinetic friction between Mb andthe horizontal surface.
(c) Mass Ma is now increased by 0.70 kg. Calculate the magnitudeof the acceleration of Mb.
