Answer:
1.5 km/s²
Explanation:
Given that:
a car starts from rest; it means the initial velocity (u) = 0 km/hr = 0 m/s
after time (t) = 20 seconds
the final velocity = 108 km/hr = 30 m/s
The acceleration (a) of the car can be determined by using the formula:
[tex]a = \dfrac{v-u}{t}[/tex]
[tex]a = \dfrac{30\ m/s -0 \ m/s}{20 \ s}[/tex]
[tex]a = \dfrac{30 \ m/s}{20 \ s}[/tex]
a = 1.5 km/s²
