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 forces

According to Newton's second law \(F = ma\). The length of the downward - pointing arrow (force) is longer than the upward - pointing arrow. So, the net force \(F_{net}=F_{down}-F_{up}\) is in the downward direction.

Step2: Relate net force and acceleration

Since \(F_{net}
eq0\), the object has an acceleration \(a=\frac{F_{net}}{m}\) (where \(m\) is the mass of the object). The acceleration is in the opposite direction of the velocity (the object is moving upward). When acceleration is opposite to velocity, the object is slowing down. Also, because \(F_{net}
eq0\), the forces are unbalanced.

Answer:

Slowing Down, Unbalanced
