A 2-Kg block sits on a 4 Kg block that is on a frictionless table. The coefficient of friction between the blocks are μs = 0.3 and μk = 0.2.
a. According to the observer (with its reference attached to the floor): if a strong-enough force F is applied to the mass M2, the maximum acceleration that block m1 can possibly have is
a. 3m/s2
b. 1.5m/s2
c. 1 m/s2
d. 18 m/s2
e. NA
b. If F is strong enough to cause the masses to slide against each other, the acceleration of block n1 will be (according to a reference attached to the floor):
a. 1 m/s2
b. 1.5 m/s2
c. 2 m/s2
d. 18 m/s2
e. NA
