Question

What is the average acceleration of a car that starts from

and moves straight ahead at 18 m/s in 12 s?​

Answer 1

1.5m/s^2

Step-by-step explanation:

In the picture above.

Answer 2

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
