Question

If an object is shot upward with initial velocity in feet per second the velocity in feet per seconds is given by the formula V equals Leo March 32 where T is time in seconds find the initial velocity of an object with a velocity after three seconds is 24 feet

Answer 1

`v=v_0-32t`

we can replace the velocity (24ft/s) and the time(3s)

`(24)=v_0-32(3)`

simplify

`24=v_0-96`

and solve for v0

`\begin{gathered} 24+96=v_0 \\ \\ v_0=120 \end{gathered}`

then the initial velocity is 120 feet per second
