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 is the starting velocity of a falling object, V is the final velocity of the falling object, and t is the time for the object to fall.

Respuesta :

Using the equation of motion:
[tex]V=V_0+32t[/tex]

Plug in the final velocity:[tex]V=125[/tex]
and the initial velocity:[tex]V_0=25[/tex]

Then you would get:
[tex]125=25+32t\\ 125-25=32t\\ 100=32t\\ t= \frac{25}{8} \\ t=3.125[/tex]
