Question

object a represents a light object (weighs less than normal)
before force: object a is traveling at medium speed to the right
during force: a medium force is exerted on object a to the left
after force: object a is thrown in the other direction, now traveling slowly to the left
correct
not correct

Explanation:

Step1: Analyze the force - motion relationship

According to Newton's second law \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration). The object is light (small \(m\)). A medium force \(F\) to the left is applied. Since \(a=\frac{F}{m}\), a small - mass object will have a relatively large acceleration.

Step2: Consider the initial and final motion

The object was moving to the right (initial velocity \(v_{i}>0\)). A force to the left (\(F < 0\)) causes deceleration. For a light object, a medium force can cause a significant change in velocity. The final velocity is to the left (opposite direction of initial velocity). Also, the change from medium - speed right to slow - speed left is consistent with the force - mass relationship.

Answer:

Correct
