A)
TrueFalseGreater thanLess thanEqual to Tw is .... Tz
TrueFalseGreater thanLess thanEqual to Ma accelerates downward
TrueFalseGreater thanLess thanEqual to Mb*g is .... Ty.
TrueFalseGreater thanLess thanEqual to Tz is .... Ty
TrueFalseGreater thanLess thanEqual to Mc is moving to the left
TrueFalseGreater thanLess thanEqual to The magnitude of the total force on Mc is .... 0

B)Calculate the coefficient of kinetic friction between Mc and the horizontal surface.

C)Mass Mb is now decreased by 0.50 kg. Calculate the magnitude of the acceleration of Mc.

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.
