Three blocks are pushed up a frictionless plane that is inclined at an angle of 30 degrees with respect to the horizontal as shown below. The blocks move together with constant acceleration a = 3.0 m/s2. The masses of the blocks are: MA = MC = 1 kg, and MB = 2 kg.
M=Mass
The magnitude of the force that block A exerts on Block B is greater than the magnitude of the force that block B exerts on Block A.
TRUE
FALSE
Compare FAonB, the force Block A exerts on Block B, to FConB, the force Block C exerts on Block B,
FAonB < FConB
FAonB = FConB
FAonB > FConB
What is the value of F, the external force that is exerted on Block A?
F = 3.0 N
F = 4.9 N
F = 12.0 N
F = 31.6 N
F = 39.2 N
