Answer:

See Explanation

Explanation:

The question is incomplete as the value of s(t) is missing;

However, the following explanation will guide you;

I'll continue my explanation with the following assumption that:

$s(t) = 64 + 4(t-6)$

Required

Determine the velocity at t = 8

To do this; first calculate s(t) by substituting 8 for t in $s(t) = 64 + 4(t-6)$

$s(8) = 64 + 4(8- 6)$

$s(8) = 64 + 4(2)$

$s(8) = 64 + 8$

$s(8) = 72$

Next, is to calculate the velocity by dividing s(t) by t where t = 8

i.e.

$Velocity = \frac{s(t)}{t}$

Substitute 8 for t

$Velocity = \frac{s(8)}{8}$

Substitute 72 for s(8)

$Velocity = \frac{72}{8}$

$Velocity = 9\ ft/s$

<em>So: all you need to do is first calculate s(8), then divide the resulting value by 8 to get your result</em>
