Solution:
In this question we have given,
initial velocity,u = 0
final velocity, v = 1m/s
displacement =.5mm (Because 1mm=.001m)
We have to find
1.acceleration
2. Time
1. we know third equation of motion is given as,
[tex]v^{2} =u^{2} + 2as[/tex]............(1)
Put values of v,u and s in equation (1)
[tex][tex]s=1^{2} = 0^{2} +2X.0005Xa\\1= .001a\\therefore, a = 1/.001\\ a= 1000m/s^{2}[/tex]
2. We know First equation of motion is given as
[tex]v=u+at[/tex]......................(2)
put values of v, u and a in equation(2)
[tex]1= 0 + 1000t\\t= 1/1000\\t= 0.001s[/tex]
