Question

a train runs between two stations stopping at each. Its velocity V km/min, t minutes after leaving the first station, is given by v = 0.12t(6-t)

Answer 1

find the time taken to travel between the two stations

Answer 2

if something is stopped, its velocity is 0 right?

Answer 3

yes

Answer 4

then for which ts does V = 0?

Answer 5

for t=0 and t=6 obviously...

Answer 6

obviously lol

Answer 7

so after first starting it stops again after 6 minutes

Answer 8

i was going to say 360 seconds, but 6 minutes sounds adequate

Answer 9

yup - lol

Answer 10

yup...the time difference between the two stations is 6mins...when the train travels at Vkm/min.

Answer 11

there you go

Answer 12

LOL @Akshat4-10 and @cwrw238 for impersonating me hahahas
thanks guys ;)

Answer 13

so for this question how would we find
ii- the maximum positive velocity attained
iii- the distance between the two stations
