Question

What is the acceleration of a the BMW i8 Roadster that goes from 0 to 60 mph in 3.8 seconds? A) in mi/h/s and b) in m/s^2

Answer 1

a) 15.78 mi/h/s

b) 7.105 m/s^2

Step-by-step explanation:

a) It is given that speed changes from 0 to 60 miles per hour (mph)

Acceleration is equal to change in speed divided by time

`a = (60-0)/(3.8) \\a = 15.78` mi/h/s

b)

1 mile/h = 0.45 m/s

Acceleration in m/s^2

`15.78 * 0.45 = 7.105` m/s^2
