Question

A car started from the state of rest. if the acceleration of the car becomes 5m/s² after 10 seconds of moving, what will be its final velocity?

Answer 1

In order to calculate the final velocity, we can use the formula below:

$V=V_0+a\cdot t$

Where V is the final velocity after t seconds, V0 is the initial velocity and a is the acceleration.

So, for V0 = 0, a = 5 and t = 10, we have:

$\begin{gathered} V=0+5\cdot10 \\ V=50\text{ m/s} \end{gathered}$

The final velocity is 50 m/s.
