Question

1. the graph represents the motion of a car traveling horizontally along a straight road in the positive direction. what is the displacement of the car between t = 1 s and t = 4 s? position - time graph position (m) 0 10 20 30 1 2 3 4 time (s) clear all 10 m 0 m 5 m 20 m

Explanation:

Step1: Identify position at t = 1s

From the graph, at t = 1s, the position $x_1$ is 10m.

Step2: Identify position at t = 4s

From the graph, at t = 4s, the position $x_2$ is 0m.

Step3: Calculate displacement

Displacement $\Delta x=x_2 - x_1$. Substitute $x_1 = 10m$ and $x_2=0m$ into the formula: $\Delta x=0 - 10=- 10m$. The magnitude of displacement is 10m.

Answer:

10 m
