A train starting from rest moves with a uniform acceleration of `0.2 m//s^(2)` for 5 minutes . Calculate the speed acquired and the distance travelled in this time.

A

60 m/s , 1000 m

B

40 m/s , 2000 m

C

60 m/s , 9000 m

D

NONE

Text Solution

Verified by Experts

The correct Answer is:
C
Here, `u = 0, a = 0.2 m//s^(2), t = 5 min = 5 xx 60s`
`v = ?, s = ?`
From `v = u + at = 0 + 0.2 xx 300 = 60 m//s`
From `s = ut + (1)/(2)at^(2)`
`s = 0 + (1)/(2) xx 0.2(300)^(2) = 9 xx 10^(3)m`
