Question

A train accelerates uniformilly from 36km/h to 72km/h in 20 second find the distance travelled by the train solve it

Answer 1

Answer:

The distance travelled by the train is 300m.

Explanation:

The initial speed (u)=36km/h=10m/s

The final speed (v)=72km/h=20m/s

Time (t)=20s

From the laws of kinematics we get

v = u + at

putting the values we get a=0.5m/s²

From another law of kinematics we get

v²=u²+2as

putting the values we gets=300 m.
