A particle is moving with uniform acceleration along a straight line. Its velocities at A & B are respectively `7 m//s` & `17 m//s`. M is mid point of AB. If `t_(1)` is the time taken to go from A to M and `t_(2)` the time taken to go from M to B, the ratio `t_(1)/t_(2)` is equal to :-

A

`3:2`

B

`3:1`

C

`2:1`

D

`2:3`

Text Solution

Verified by Experts

The correct Answer is:
A

`v_(m)^(2)=(7)^(2)+2xxaxx x , v_(m)=13 m//s`
`(17)^(2)=(7)^(2)+2xxaxx2x`
`(13-7)/a=t_(1), t_(2)=(17-13)/a, t_(1)/t_(2)=6/4=3/2`
