Question

1.Draw displacement - time graph for the following cases: (a) Two cars A and B , moving in opposite directions on a straight line path with velocity 10 m/s , with an initial separation of 1000 m.
please answer fast and correct.​

Answer 1

To draw:

Displacement-Time graph for two cars A and B moving in opposite directions on a straight line with uniform velocity of 10 m/s and initially separated by 1000 m.

Solution:

We will draw both the displacement time curves on the same graph which would help us in comparison for car A and B.

Displacement is a vector. Since cars A and B are moving in opposite directions, let Car A have positive Displacement and car B have negative Displacement.

Since the cars are moving with uniform velocity, the displacement time curve will be represented as a straight line with positive slope for car A and negative slope for car B.
