Question

a cup of coffee is sitting on a table in a recreational vehicle (rv). the cup slides toward the rear of the rv. according to newton's first law, which one or more of the following statements could describe the motion of the rv? (a) the rv is at rest, and the driver suddenly accelerates. (b) the rv is moving forward, and the driver suddenly accelerates. (c) the rv is moving backward, and the driver suddenly hits the brakes. (a) a (b) b (c) c (d) a and b (e) a, b, and c

Answer 1

According to Newton's first law of motion, the RV is moving forward, and the driver suddenly accelerates.

Step-by-step explanation:

According to Newton's first law of motion, an object at rest remains at rest, and an object in motion remains in motion at a constant velocity, unless acted on by a net external force. In this case, the cup of coffee is sliding towards the rear of the RV, indicating that the RV is accelerating forward. Therefore, the correct statement that describes the motion of the RV is (b) the RV is moving forward, and the driver suddenly accelerates.
