Velocity(Speed with Direction)

Q. An object travels 20m in 5 seconds and then another 40m in next 5 seconds. What is the average speed of the object?

1. 12m/s
2. 6m/s
3. 2m/s
4. 0 m/s

Q.

What are the uses of displacement-time graph?

Q.

The figure given shows the displacement - time graph of four children A, B, C, and D. Which child has the highest velocity?

Q. A body covers first $\frac{1}{3}$ part of its journey with a velocity of 2 m/s, next $\frac{1}{3}$ part with a velocity of 3 m/s and rest of the velocity 6 m/s. The average velocity of the body will be

1. $\frac{11}{3}$ m/s
2. 3 m/s
3. $\frac{8}{3}$ m/s
4. $\frac{4}{3}$ m/s

Q.

Which of the following relation represents the relationship between the average speed, time, and distance correctly?

1. Average speed = distance × time

2. Average speed = $\frac{\mathrm{Total}\mathrm{distance}}{\mathrm{Total}\mathrm{time}}$

3. Time = average speed + distance

4. Distance = average speed × (time)²
