A train starting from rest moves with a uniform acceleration of 0.2 m/s2 for 5 minutes. Calculate the speed acquired and the distance travelled in this time.

Answer :

A = 0.2 m/s2(Given)

T = 5 mins(Given)

We know 1 Minute= 60 seconds
∴ 5 Minute= 300 seconds

U = 0 m/s(As the train is starting from rest)


On applying the formula v= u+at we get

v= 0+ 0.2m/s2×300 seconds
v= 60 m/s

On applying the formula v2 -u2= 2as we get

(60)2-(0)2= 2×0.2×s

s=

=9000m

s= 9km
