after travelling a distance of 100 m. If speed of car
is halved and same retarding acceleration is applied
then it stops after travelling a distance of
[NCERT Pg. 50]
(1) 25 m
(2) 50 m
(3) 75 m
(4) 100 m​

Answer 1

Explanation:

nce of 100 m. If speed of car is halved and same retarding acceleration is applied then it stops after travelling a distance of

use third equation of motion here. for first part, v.v-u.u=2a(100)...........(1) for second part, v.v -u.u/4=2as...........(2) from equation (1) and (2), s=25m

Answer 2

Answer:

We use third equation of motion here for first part , v. v - u. u =2as (100) ..............(1) for...

second part v. v - u. u /4 = 2as........... (2) from....

equation (1) and ( 2), 5=25m...
