Explanation:

In the picture above.

Answer 2

Answer:

The car is moving at an average acceleration of 1.5 m/s2

Explanation:

According to the question,

The car is moving in a straight road

The speed of the car = 18 m/s

Time is given (t) = 12 s

Acceleration is the rate of change of speed with respect to time. It is computed by the formula;

$\text { Acceleration }=\frac{\text {Speed }}{\text {Time}}$

Acceleration = (18 m/s)/(12 s)= 1.5 m/s2

$\text { Acceleration }=\frac{18 \mathrm{m} / \mathrm{s}}{12 \mathrm{s}}=1.5 \mathrm{m} / \mathrm{s}^{2}$

Therefore, the car is moving at an average acceleration of 1.5 m/s2
