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;
[tex]\text { Acceleration }=\frac{\text {Speed }}{\text {Time}}[/tex]
Acceleration = (18 m/s)/(12 s)= 1.5 m/s2
[tex]\text { Acceleration }=\frac{18 \mathrm{m} / \mathrm{s}}{12 \mathrm{s}}=1.5 \mathrm{m} / \mathrm{s}^{2}[/tex]
Therefore, the car is moving at an average acceleration of 1.5 m/s2
