Question

A Porsche can go from 50m/s to 160m/s in 3s. What is the acceleration?

A. 36.67 m/s^2
B. 10 m/s^2
C. 70 m/s^2
D. 53.33 m/s^2

Answer 1

The acceleration of the Porsche is 36.67 m/s²

Step-by-step explanation:

The acceleration can be calculated using the formula:

acceleration = change in velocity / time

Given that the change in velocity is 160 m/s - 50 m/s = 110 m/s and the time is 3 seconds, we can substitute these values into the formula:

acceleration = 110 m/s / 3 s = 36.67 m/s²

Therefore, the correct answer is A. 36.67 m/s².
