Question

A car traveling 15 m/s sees the light turn yellow and decides to gun it through the intersection to make it. If the car reaches 22 m/s after accelerating for 2.5 s, how fast did it accelerate?

Answer 1

The car accelerated at a rate of 2.8 m/s².

Step-by-step explanation:

To find the acceleration of the car, we can use the formula: acceleration = (final velocity - initial velocity) / time. In this case, the initial velocity is 15 m/s, the final velocity is 22 m/s, and the time is 2.5 seconds. Plugging in these values, we get: acceleration = (22 m/s - 15 m/s) / 2.5 s = 2.8 m/s². Therefore, the car accelerated at a rate of 2.8 m/s².
