Question

Example 8.5 A train starting from rest
attains a velocity of 72 km h in
5 minutes. Assuming that the
acceleration is uniform, find (i) the
acceleration and (ii) the distance
travelled by the train for attaining this
velocity.
​

Answer 1

Answer:Initial velocity(u)=0

Final velocity (v)=72*5/18m/sec=20 m/sec

Time (t)=5*60 s=300s

Acceleration (a)=(v-u)/t=20/300m/sec^2=1/15m/sec.
