Question

A driver of a train travelling at a speed of 15m/s applies brake and retards the train uniformally the train stop in. 5s, another train B is travelling on a parallel track with a speed of 10m/s . It's driver applies brake and the train stop in. 10s regarding uniformaly Find. Plot speed time graph for train A and B

Answer 1

To get the distance travelled by the two trains we will use the formula :

Distance = speed × time

Train A:

15 × 5 = 75 M

Train B:

10 × 10 = 100 M

We are plotting the graph of velocity against time.

Find the graph in the image below.

Since it is retardation, the graphs slope downwards from initial velocities to zero.

Answer 2

Answer:
