Answer
Explanation:
Step1: Recall Newton's first law
According to Newton's first - law of motion, an object moving at a constant velocity has no acceleration ($a = 0$).
Step2: Apply Newton's second law
Newton's second law is $F_{net}=ma$, where $m$ is mass and $a$ is acceleration. Since $a = 0$ and $m=0.5$ kg, then $F_{net}=0.5\times0 = 0$ N.
Answer:
Zero N
