Question

a train starting from rest attains a velocity of 20m/s in 2 min. assuming that the acceleration is uniform, find (1) the acceleration (2) distance travelled by the train, while it attained this velocity ​

Answer 1

Answer:

(1)1/6m/s^2

(2)2400m

Explanation:

u=0 m/s

v=20 m/s

t=2 min=120 s

(1)acceleration=(v-u)/t

=(20-0)/120

=20/120

=1/6 m/s^-2

(2)distance=speed×time

=20×120

=2400m
