QUESTION:
Figure 5-22 shows overhead views of four situations in which forces act on a block that lies on a frictionless floor. If the force magnitudes are chosen properly, in which situations is it possible that the block is (a) stationary and (b) moving with a constant velocity?
ANSWER:Step 1 of 4
For, the constant velocity or remaining stationary of an object is possible when the net force on the object is zero.
The Free-body-diagram of the forces in the first case is shown below:
The force is balance by the force but there is a net vertical force.
The net force on the block is not zero here, so there is a net acceleration.
