A particle moves on a straight line, with uniorm acceleration `-5m//s^(2)`. Distance travelled by it in three consecutive intervals of `1s` are in ratio of `3:1:1`. Then the total distance travelled in three seconds is:

A

`25m`

B

`12.5m`

C

`22.5m`

D

`20m`

Text Solution

Verified by Experts

The correct Answer is:
B
For backward journey `x=1/25(1)^(2)=5/2m`
So, total distance `=5x`
`=25/2m`
