Question

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.

3.125 seconds
4800 seconds
4.69 seconds
3200 seconds

Answer 1

\(\color{#000000 }{ \displaystyle v=v_0+32t }\)

Answer 2

All you need to do is to plug in your numbers.
The final velocity is 125 ft/s, and the initial velocity is 25 ft/s.

\(\color{#000000 }{ \displaystyle v=125~{\rm ft/s} }\)
\(\color{#000000 }{ \displaystyle v_0 =25~{\rm ft/s} }\)

Answer 3

Then, just solve for time (t).

Answer 4

ok thank you
