Answer in units of m. Your answer must
be within 3.0%
Answer in units of m

Answer 1

86.1125 meters

Step-by-step explanation:

Here is what we are given:

Initial Velocity - 0 m/s

Acceleration - 2.5
`m/s^2`

Time - 8.3 s

We can use this motion equation. This equation is derived from one of the common kinematics equations. It may not look familiar.

`x=0.5t^(2)a`

We can now substitute our values into the equation.

`x=0.5*8.3^(2)*2.5`

`x=0.5*68.89*2.5`

`x=86.1125`
