In order to move to the left, it'd have to have a force of friction to the direction of the left. However, wouldn't that imply that it'd accelerate instead of going at constant speed? I assumed that in order for block B to not fall off, it'd have to have the same speed/acceleration. In this...
Homework Statement
Block A slides on a frictionless ramp, as shown (in the attachment). At the instant, the block is moving up the ramp with speed V. Block B rests on top of A, and does not slip, due to friction between A and B. What is the direction of the friction force acting on B...
