Question

the diagram below represents the forces acting upon a leftward - 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

The upward and downward forces are equal in length (strength). So, \( F_{up}=F_{down}\), and there is no acceleration in the vertical direction.

Step2: Analyze horizontal forces

The left - ward force is longer (stronger) than the right - ward force. So, \( F_{left}>F_{right}\). According to Newton's second law \(F = ma\) (where \(F\) is the net force, \(m\) is mass, and \(a\) is acceleration), the net force \(F_{net}=F_{left}-F_{right}\) is in the left - ward direction. Since the object is already moving left - ward and there is a net force in the same direction, the object is speeding up. Also, because \(F_{left}
eq F_{right}\), the forces are unbalanced.

Answer:

Speeding Up, Unbalanced
