Question

Tariah is riding on her bike at 4m/s (North). If she accelerates at a rate of 1.5 m/s^2 for 2 s, what is her final velocity?

Answer 1

7 m/s

Explanation:

Given:

Initial velocity (u) = 4 m/s

Acceleration (a) = 1.5 m/s^2

Time (t) = 2 s

We can calculate the final velocity using the following formula:

`v=u+a\cdot t`

We replace and calculate the value of the final velocity:

`\begin{gathered} v=4+2\cdot1.5 \\ v=4+3 \\ v=7\text{ m/s} \end{gathered}`

The final velocity is equal to 7 m/s.
