Question

A car moving initially at 30 m/s accelerates up to 60 m/s during the course of 5 seconds. The average acceleration of the car is m/s².

A) 6 m/s²
B) 12 m/s²
C) 6.67 m/s²
D) 10 m/s²

Answer 1

The average acceleration of the car is 6 m/s².

Step-by-step explanation:

To calculate the average acceleration, we use the formula:

average acceleration = (change in velocity) / (time)

In this case, the change in velocity is 60 m/s - 30 m/s = 30 m/s, and the time is 5 seconds. Plugging these values into the formula, we get:

average acceleration = 30 m/s / 5 s = 6 m/s²

Therefore, the average acceleration of the car is 6 m/s². So the correct answer is A) 6 m/s².
