Question

the diagram below represents the forces acting upon an upward - moving object. each arrow represents a force; the length of the arrow represents the strength of the force. is this a speeding up, slowing down, or constant speed motion? speeding up slowing down constant speed is the object experiencing balanced or unbalanced forces? balanced unbalanced

Explanation:

Step1: Analyze the net force

Since the upward force (longer arrow) is greater than the downward force (shorter arrow), the net force is upward. According to Newton's second law \(F = ma\), when there is a net force (\(F
eq0\)), there is an acceleration (\(a
eq0\)).

Step2: Determine the motion type

The object is moving upward and has an upward acceleration (because \(F_{net}>0\) and \(a=\frac{F_{net}}{m}\), \(m>0\)). So it is speeding up.

Step3: Determine force balance

When forces are balanced (\(F_{net} = 0\)), there is no acceleration (\(a = 0\)). Here \(F_{net}
eq0\), so the forces are unbalanced.

Answer:

1. Speeding Up
2. Unbalanced
