Question

the diagram below represents the forces acting upon a rightward - 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 vertical forces

In the vertical direction, the upward - acting force and the downward - acting force are of equal length. So, \(F_{up}=F_{down}\), and the net vertical force \(F_{net - vertical}=F_{up}-F_{down}=0\).

Step2: Analyze horizontal forces

In the horizontal direction, the right - acting force is longer than the left - acting force. Let the right - acting force be \(F_{right}\) and the left - acting force be \(F_{left}\). Then \(F_{net - horizontal}=F_{right}-F_{left}>0\). According to Newton's second law \(F = ma\) (\(F\) is the net force, \(m\) is the mass, and \(a\) is the acceleration). Since \(F_{net - horizontal}>0\) and \(m>0\), \(a=\frac{F_{net - horizontal}}{m}>0\). The object is moving to the right, and a positive acceleration in the direction of motion means the object is speeding up. Also, because \(F_{net - horizontal}
eq0\), the forces are unbalanced.

Answer:

Speeding Up, Unbalanced
