Question

S=ut+1/2at²

u=3 a=-12 t=1/3
work out the value of s

Answer 1

`s = ut + (1)/(2) a {t}^(2) \\ s = (3 * (1)/(3) ) + ( (1)/(2) * -12 * {( (1)/(3)) }^(2) ) \\ s = (1) + ( -(2)/(3) ) \\ s = - (1)/(3) \\ s = -(1)/(3) \: metres`

Answer 2

Explanation:

s = ut + 0.5at²

= (3)(1/3) + 0.5(-12)(1/3)²

= 1 - 2/3

= 1/3

The value of s is 1/3.
