Question

Using the kinematic expression shown in the content, $s = ut + 	frac{1}{2}at^2$, what is the contribution of the acceleration term alone when $a = 4\,	ext{m s}^{-2}$ and $t = 8\,	ext{s}$?

Accepted Answer

C. $128\,	ext{m}$

The acceleration term is $	frac{1}{2}at^2 = 	frac{1}{2}	imes 4 	imes 8^2 = 2	imes 64 = 128\,	ext{m}$. So option C is correct.

Answer

$64\,	ext{m}$

Answer

$96\,	ext{m}$

Answer

$160\,	ext{m}$
