If u=0, make t the subject of the following equation: s=ut+1/2at^2 Please look at image.

Sladkaya [172]

Answer:

$t=\sqrt{\dfrac{2s}{a}}$

Step-by-step explanation:

The given equation is :

$s=ut+\dfrac{1}{2}at^2$

Where

s is displacement

u is the initial velocity

a is acceleration

t is time

If u = 0, the above equation become,

$s=\dfrac{1}{2}at^2\\\\t^2=\dfrac{2s}{a}\\\\t=\sqrt{\dfrac{2s}{a}}$

Hence, the value of t is equal to $\sqrt{\dfrac{2s}{a}}$ .
