A train accelerating uniformly passes three successive kilometre posts at time `t = 0, t= 75` and `t = 125` (all in second), In respect of this motion, which of the following statement are true ?

A

The acceleration of the train is `((8)/(75)) m//s^(2)`

B

The speed at the last of the three posts is 22.67 m/s

C

The initial velocity of the train is 10 m/s

D

The train will travel the next one kilometre in 15 second

Text Solution

Verified by Experts

The correct Answer is:
A, D
`1 + s = u xx 75 + (1)/(2) a xx (75)^(2)`
`2 + s = xx 125 + (1)/(2) a xx (125)^(2)`
