Question

15 what is the velocity of the motion depicted in this graph? - 7 m/s - 1 m/s 7 m/s 1 m/s

Explanation:

Step1: Recall the formula for velocity

Velocity \(v=\frac{\Delta x}{\Delta t}\), where \(\Delta x = x_{2}-x_{1}\) and \(\Delta t=t_{2} - t_{1}\)

Step2: Identify two points on the graph

Let's take \((t_{1},x_{1})=(0,7)\) and \((t_{2},x_{2})=(7,0)\)

Step3: Calculate \(\Delta x\) and \(\Delta t\)

\(\Delta x=0 - 7=-7\) m, \(\Delta t=7 - 0 = 7\) s

Step4: Calculate velocity

\(v=\frac{\Delta x}{\Delta t}=\frac{-7}{7}=- 1\) m/s

Answer:

-1 m/s
