Question

Acar moving south speeds up from 10 m/s to 40 mls in 15 seconds. What is the car's acceleration? ​

Answer 1

The car's acceleration is 2 m/s².

Step-by-step explanation:

The acceleration of the car can be determined using the formula: acceleration = (final velocity - initial velocity) / time. Plugging in the values provided by the question, the calculation would be:

acceleration = (change in velocity) / (time)

In this case, the change in velocity is 40 m/s - 10 m/s = 30 m/s, and the time is 15 seconds. So, the acceleration is:

acceleration = 30 m/s / 15 s = 2 m/s²

Therefore, the car's acceleration is 2 m/s².
