Answer 1

Answer:

zero metres

Explanation:

t=√x+3

⇒√x=t-3

⇒x=(t-3)²

Differentiate with respect to t

dx/dt=2(t-3)                ( Math help : d/dx (x-a)^n = n(x-a)^n-1)

dx/dt is nothing but velocity(v)

therefore, v=2(t-3),

Given v=0

⇒2(t-3)=0

∴t=3 seconds

substitute it in given equation,

3=√x+3

√x=0

x=0 m

Therefore its displacement is zero metres.
