Question

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

Answer 1

`t=\sqrt{(2s)/(a)}`

Explanation:

The given equation is :

`s=ut+(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=(1)/(2)at^2\\\\t^2=(2s)/(a)\\\\t=\sqrt{(2s)/(a)}`

Hence, the value of t is equal to
`\sqrt{(2s)/(a)}`.
