Question
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, (k0). 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 and the horizontal surface.
(c) Mass Ma is now increased by 0.70 kg. Calculate the magnitude of the acceleration of Mb.
Explanation / Answer
part a i) True. The tension is equal throughout the rope ii) True. Equal. It is moving at constant speed so there is no net acceleration. iii) False. See previous post. iv) True. Ma is heavier than Mc. v) True. Ma is heavier than Mc. vi) True. Equal. The whole system is moving at constant speed so there will be no net acceleration. Thus, the forces are equal.
