Explanation:

answers in short----

1.spectators are in test so time taken by the ball is small so rate of change in momentum is large, hence force applied is large

on the other hand players drew their hand back while catching the ball hence rate of change in momentum is less and force applied is less.

2. answer for newton's first law, force applied

3.this is due to inertia of motion backseater tends to be in motion when the bike stops.

4 . due to inertia of rest, dust tends to be in rest when carpet is in motion. so it releases dust.

5.weight S.I. unit - kg

. 6.inertia

7)5×0.20 kgms^-1= 1kgms^-1

8.) theoretically no force is acting on the because of no change in momentum.

9. force acting on the body is rate of change in momentum.

10. force

11. momentum = mass× velocity Try yourself now

12.24 N

13. for every action there is equal and opposite reaction of same magnitude.

14. answer same as Q4

15. try it yourself. use formula as in ans 11 and 9

answer initial- 500kgms^-1 final - 800 kgms^-1

force - (800- 500)/6 = 50N

16. acceleration

17. pressing the ground is action and runner moves forward is reaction

that's all Mark and follow me if you like.
