Calculate the time required for an object to increase velocity from 25 ft/s to 125 ft/s. Use the formula V = V0 + 32t, where V0

Alborosie

Using the equation of motion:
$V=V_0+32t$

Plug in the final velocity: $V=125$
and the initial velocity: $V_0=25$

Then you would get:
$125=25+32t\\
125-25=32t\\
100=32t\\
t= \frac{25}{8} \\
t=3.125$
