Question

a train is moving with the velocity of 10m/s. it's acceleration is 4 meter per second sqaure, after 5 seconds. find the distance cause by the train.​

Answer 1

Answer:

s=u+at

=s=10+4×5

=s=10+20

=30

inital vel=10m/s

time=5sec

distant=s

Answer 2

Given : A train is moving with the velocity of 10m/s. it's acceleration is 4 m/s², after 5 seconds. Find the distance cause by the train.

Solution : According to the question, here we are given that the initial velocity of the train is 40m/s. The time taken is 5s and the acceleration is 4m/s². Now, as per the situation we need to apply the second equation of motion.

Equation : S = ut + ½at²

Putting the values we can get the distance caused by the train

• S = 40(5) + ½ × 4(5)²

• S = 200 + 2(25)

• S = 200 + 50

• S = 250

Henceforth, Distance caused by the train is 250m.
