Question

) Find out time taken by a train to reach a
velocity 0.2 m/s2 if it start from the state of
rest and travels with an acceleration of
0.2 m/s2​

Answer 1

I don't know if data is correct, but according to the given conditions, answer will be:

Final velocity (V) = 0.2, initial velocity (U)= 0

(being at rest)

acceleration (a)= 0.2

now w.k.t; v = u + at

t=(v-u)/a

t= (0.2 -0) / 0.2

t= 1 s

Answer 2

$0.2 = \frac{0.2 - 0}{t} \\ t = \frac{0.2}{0.2} = 1$

thus , the acceleration is 1
