Answer:

a) 15.78 mi/h/s

b) 7.105 m/s^2

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

[tex]a = \frac{60-0}{3.8} \\a = 15.78[/tex] mi/h/s

b)

1 mile/h = 0.45 m/s

Acceleration in m/s^2

[tex]15.78 * 0.45 = 7.105[/tex] m/s^2
