Question

11. A train moving with a uniform acceleration, crosses station A with a velocity of 108 kmp
and another station B with a velocity of 144 kmph. The time taken for the train to trave
from A to B is 20 minutes. The distance between the two stations is
18.
1) 24 km
2) 42 km
3) 32 km
4) 40 km
12. Given that s=5t+8t (in SI unit). Then the initial velocity and acceleration are
1) 5 ms! 8 ms? 2) 5 ms !, 4 ms 2 3),10 ms !, 16 ms 4) 5 ms, 16 ms 2 19.
13. A particle, initially at rest starts moving with a uniform acceleration 'a'. The ratio of the
distances covered by it in first second and the first 3 s is
1) 1:3
2)1:5
3) 1:7
4) 1:9
