Answer :
Final answer:
The acceleration of the car is determined using the formula a = (Vf - Vi) / t, where Vf is the final velocity, Vi is the initial velocity, and t is the time. Considering the values given, the acceleration comes out to be approximately 1.95 m/s².
Explanation:
The subject matter being discussed here pertains to acceleration, an important concept in physics. It's a measure of how quickly an object changes its velocity. In this scenario, the final velocity is 35.9 mi/hr (we have to convert it to m/s as asked to answer in MKS units, so approximately 16.03 m/s), and the car started at rest, so the initial velocity is 0 m/s. The time taken is 8.2 seconds.
The formula for acceleration is:
a = (Vf - Vi) / t
Where:
- Vf is the final velocity,
- Vi is the initial velocity, and
- t is the time elapsed.
Plugging in your values gives us:
a = (16.03 m/s - 0 m/s) / 8.2 seconds = 1.95 m/s².
