Pulling Two Blocks
In the situation shown in the figure, a person is pulling with a
constant, nonzero force F⃗ on string 1, which is attached
to block A. Block A is also attached to block B via string 2, as
shown.
For this problem, assume that neither string stretches and that
friction is negligible. Both blocks have finite (nonzero) mass.

Two horizontal forces, P and Q, are acting on a block that is placed on a table. We know that P = 2.10î + 4.25k N but the magnitude and direction of Q are unknown. The block moves along the table. Assume there is no friction between the object and the table. Here the mass of the block is 4.55 kg. (a) Determine the force Q when the block moves with constant velocity. Express your answer in vector form. Q...
