Question

jordan is riding up in an elevator in a tall building. the elevator and jordan have a combined weight of 12,000 newtons. a cable pulls the elevator upward with a force of 12,000 newtons.
complete the sentence.
as the elevator goes up, the magnitude of its velocity ______.
increases decreases does not change

Explanation:

Step1: Identify vertical forces

The upward force from the cable is $F_{up}=12,000\ \text{N}$, and the downward weight is $F_{down}=12,000\ \text{N}$.

Step2: Calculate net force

Net force $F_{net}=F_{up}-F_{down}=12,000 - 12,000=0\ \text{N}$.

Step3: Relate net force to acceleration

By Newton's second law $F_{net}=ma$, so $a=\frac{F_{net}}{m}=0\ \text{m/s}^2$.

Step4: Relate acceleration to velocity

Zero acceleration means velocity magnitude is constant.

Answer:

does not change
