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 they cancel each other out vertically.

Step2: Analyze horizontal forces

The left - ward force (force on the object moving in the left direction) is longer (stronger) than the right - ward force. Let the left - ward force be \( F_{left} \) and the right - ward force be \( F_{right} \), then \( F_{left}>F_{right} \). The net force \( F_{net}=F_{left}-F_{right}\) is in the left direction. According to Newton's second law \( F = ma\) (where \( F\) is the net force, \(m\) is the mass of the object, and \(a\) is the acceleration), since \( F_{net}
eq0\), there is an acceleration. The acceleration is in the direction of the net force (left - ward, same as the direction of motion of the object). When acceleration is in the same direction as the velocity of the object, the object is speeding up. Also, since \( F_{net}
eq0\), the forces are unbalanced.

Answer:

Speeding Up, Unbalanced
