Consider the system shown in the figure. Block A weighs 40.7 N and block B weighs 31.0 N. Once block B is set into downward motion, it descends at a constant speed. a. Calculate the coefficient of kinetic friction between block A and the tabletop. b. A cat, also of weight 40.7 N, falls asleep on top of block A. If block B is now set into downward motion, what is its acceleration magnitude? c. A cat, also of weight 40.7 N, falls asleep on top of block A. If block B is now set into downward motion, what is its acceleration direction?
Consider the system shown in the figure. Block A weighs 40.7 N and block B weighs 31.0 N. Once block B is set into downward motion, it descends at a constant speed.
a. Calculate the coefficient of kinetic friction between block A and the tabletop.
b. A cat, also of weight 40.7 N, falls asleep on top of block A. If block B is now set into downward motion, what is its acceleration magnitude?
c. A cat, also of weight 40.7 N, falls asleep on top of block A. If block B is now set into downward motion, what is its acceleration direction?
Given that:
The weight of block A is
The weight of block B is
The weight of the cat is
The gravitational acceleration is
It is required to determine the coefficient of friction between block A and the tabletop and block B's acceleration magnitude and the direction of the acceleration of block B.
