Question

can anyone please tell me?
​

Answer 1

Answer:

1. momentum

2. An odometer or odograph

3. 664m

4. Here, total distance = 18 m + 18 m = 36 m  

Total time taken = 4 s+ 2 s = 6 s  

Thus,  

average speed = 36/6 = 6 m/s  

The average speed of the object is 6 m/s

5. velocity, acceleration

6. uniform circular motion

7. Velocity of a particle is given by the slope of displacement-time graph. Since it is parallel to time axis, the slope is 0. So velocity of the particle is 0

8. speed

9. 2r

10. uniform circular motion

11.A centripetal force
