A Train Travelling at 20 M S-1 Accelerates at 0.5 M S-2 for 30 S. How Far Will It Travel in this Time ? - Science

Short Note

A train travelling at 20 m s-1 accelerates at 0.5 m s-2 for 30 s. How far will it travel in this time ?

Solution

We have to find the distance travelled by the train. We have the following information given,
So, initial velocity, (u) = 20 m/s
Acceleration, (a) = 0.5 m/s2
Time taken, (t) = 30 s
We can calculate the distance travelled by using the 2nd equation of motion,
s = ut + 1/2at^2
Put the values in above equation to find the distance travelled by the train,
(s) = 20(30) + 1/2(0.5)(30)^2
= (600 + 225) m
= 825 m

Concept: Rate of Change of Velocity
