# If a car, with an initial speed of 10 m/s, accelerates at a rate of 50 m/s/s for 3 seconds, what will its final speed be?

Dec 2, 2015

$200 \text{m/s}$

#### Explanation:

You can use the equation of motion:

$v = u + a t$

This becomes:

$v = 10 + \left(50 \times 3\right)$

$\therefore v = 200 \text{m/s}$
