a) The uniform velocity travelled by the car is 10 meters per second.

(Point b has been erased by the user)

c) The distance travelled by the car with uniform velocity is 100 meters.

Explanation:

a) Calculate the uniform velocity travelled by the car:

The uniform velocity is the final velocity (), in meters per second, of the the uniform accelerated stage:

$v = v_{o} + a\cdot t$ (1)

Where:

$v_{o}$ - Initial velocity, in meters per second.

- Acceleration, in meters per square second.

- Time, in seconds.

If we know that $v_{o} = 0\,\frac{m}{s}$ , $a = 2\,\frac{m}{s^{2}}$ and $t = 5\,s$ , then the uniform velocity is:

$v = 0\,\frac{m}{s} + \left(2\,\frac{m}{s^{2}} \right)\cdot (5\,s)$

$v = 10\,\frac{m}{s}$

The uniform velocity travelled by the car is 10 meters per second.

c) The distance travelled by the car ( $\Delta x$ ), in meters, with uniform velocity is calculated by the following kinematic expression:

$\Delta x = v\cdot t$ (2)

If we know that $v = 10\,\frac{m}{s}$ and $t = 10\,s$ , then the distance travelled is:

$\Delta x = \left(10\,\frac{m}{s} \right)\cdot (10\,s)$

$\Delta x = 100\,m$

The distance travelled by the car with uniform velocity is 100 meters.
