Question

6 multiple choice 0.5 points reading: a cart moves from x = 5 m to x = -3 m in 4 s. what is its average velocity? -8 m/s 8 m/s -2 m/s 2 m/s

Explanation:

Step1: Calculate displacement

Displacement $\Delta x = x_f - x_i = -3\ \text{m} - 5\ \text{m} = -8\ \text{m}$

Step2: Apply average velocity formula

Average velocity $v_{avg} = \frac{\Delta x}{\Delta t} = \frac{-8\ \text{m}}{4\ \text{s}}$

Answer:

-2 m/s
