Question

A car is moving down a freeway in a straight line at a constant rate of 32.0 m/s for 3 seconds. If, in 3 seconds, the speed was increased from 10.0 m/s to 50 m/s, what is the acceleration?

Answer 1

The acceleration of the car is 13.33 m/s².

Step-by-step explanation:

The acceleration can be calculated using the equation:

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

In this case, the change in velocity is 50 m/s - 10 m/s = 40 m/s, and the change in time is 3 seconds. Therefore, the acceleration is:

acceleration = 40 m/s / 3 s = 13.33 m/s²

So the acceleration of the car is 13.33 m/s².
