Question

Suppose a car is traveling at 12 m/s and increases its speed to 30 m/s, taking 15 seconds to do so. What is the acceleration of the car?

Answer 1

`\boxed{\text{\sf \Large 1.2 m/s^2 $}}`

Step-by-step explanation:

Use acceleration formula

`\displaystyle \text{$ \sf acceleration=(change \ in\ velocity)/(time \ taken) $}`

`\displaystyle a=(30-12)/(15) =1.2`

Answer 2

Acceleration: (final velocity - starting velocity) / (time)

Acceleration: (30-12)/15

Acceleration: 18/15

Acceleration: 6/5 m/s^2

Let me know if this helps!
