A particle starts from rest and moves with a constant acceleration of 0.5m/s . Calculate the time taken by the particle to cover a distance of 25m

t=10s

Explanation:

Use equation d=v1*t + 1/2a*t^2

Now rearrange for t

We also know that v1 is zero so that part v1*t will be canceled since its zero

d= 1/2 *a*t^2

dx2=at^2

d*2/a=t^2

^1/2 means square root

(d*2/a)^1/2 = t

Now plug in values

(2x25m/0.5m/s^2) ^1/2= t

(50/0.5)^1/2=t

(100)^1/2=t

+10s, -10=t

we will take +10s ofc.
