Question

This is question from cbse class 9 science physics motion

Answer 1

1. a) acceleration
 b)uniform
c)retarding
2.a=v-u/t
     =6-0/4=1.5 m/s^2
3.same as 2. but this time it will be -1.5 m/s^2
4.a)6m
b)0m
c)6m
5.add all=(6+0+6)m=12m   **if u like it please mark it as brainliest answer**

Answer 2

Answer:a) 1-uniform acceleration.

2-zero acceleration.

3-negative acceleration.

B) a=ae/bc=6/4=1.5m/s^2

C) retardation=1 m/s^2.

D) 6 m, 0 , 6m

E) 12m
