(b) An object is moving with a velocity of 6 m/s and with an acceleration of - Im/s. What will be the
(i) distance travelled by the object before it coming to rest?
(ii) time taken for coming to rest

- Initial velocity of the object, u = 6 m/s
- Acceleration of the object ,a = -1 m/s².
Since the object comes to rest, the final velocity of the object is zero.
- Final velocity, v = 0
- Let s be the distance travelled by the object.
- Let t be the time taken for coming to rest.
ii)
According to the first equation of motion,
v = u + at
The time taken by the object for coming to rest is 6 s.
I)
According to the third equation of motion,
The distance travelled by the object is 18 m.

Correct Question:-
An object is moving with a velocity of 6m/s and comes to rest with a deceleration of 1m/s². Then find the distance travelled by the object and also find the time taken by the object to come to rest.
To Find:-
- Find the distance travelled by the object.
- Time taken by the object to come to rest.
Given:-
- An object is moving with a velocity of 6m/s and comes to rest with a deceleration of 1m/s².
Solution:-
Here,
We know that
- initial velocity = 6m/s
- final velocity = 0
- acceleration = -1m/s²
Using Formula:-
Substituting value:-
Now,
We have to find the distance.
Using Formula:-
Substituting Values:-
