Question

A train starts from a station and and moves with constant acceleration for 2 minutes. If is covers a distance of 400 m in this period find the acceleration.

Answer 1

Step1 Given Data:

Time =$2minutes=120sec$

Distance = $400m$

Step2 Formula Used:

$s=\frac{1}{2}a{t}^2$ as u=0

Step3 Calculation for acceleration:

Substituting the value

$400=\frac{1}{2}a\times 120\times 120$

$a=\frac{400\times 2}{120\times 120}=0.055m/s^2$

Hence acceleration = $0.055m/s^2$
