Question

1. an object is subject to multiple forces that result in the object having horizontal and vert velocity components ( v_x ) and ( v_y ), respectively as a function of time, as shown. which of the following diagrams could represent the forces exerted on the object?

Explanation:

Step1: Analyze the horizontal velocity

The horizontal velocity \(v_x\) is constant. According to Newton's second law \(F = ma\), if \(a_x=\frac{\Delta v_x}{\Delta t}=0\), then the net horizontal force \(F_x = 0\).

Step2: Analyze the vertical velocity

The vertical velocity \(v_y\) is decreasing. So the vertical acceleration \(a_y=\frac{\Delta v_y}{\Delta t}<0\) (negative direction). By \(F = ma\), the net vertical force \(F_y<0\) (downward direction).
