A car is moving along a straight line. The displacement-time graph of the car is given below. Calculate the velocity at points A and D, given that the time interval for each segment is 0.08 s.

Here's the solution to your assignment:

a) Calculate the velocity at A and D

Step 1: Identify the length of tape segments A and D from the graph and the given time interval.
From the graph:

• Length of segment A ($L_A$) = 20 cm
• Length of segment D ($L_D$) = 80 cm From the problem statement:
• Time interval for each length ($\Delta t$) = 0.08 s

Step 2: Calculate the velocity for each segment using the formula $v = \frac{\text{length}}{\text{time interval}}$.
Velocity at A:
