Question

question 3 of 5 view policies current attempt in progress an object is moving at a constant velocity. all but one of the following statements could be true. which one cannot be true? no forces act on the object. a single force acts on the object. three forces act simultaneously on the object. two forces act simultaneously on the object.

Explanation:

According to Newton's first - law, an object moves at a constant velocity when the net force acting on it is zero. If no forces act on the object, the net force is zero. If multiple forces act and their vector sum is zero, the net force is zero. But if a single non - zero force acts on the object, there will be a non - zero net force, and the object will accelerate (change its velocity), which contradicts the object moving at a constant velocity.

Answer:

A single force acts on the object.
