Question

4. A vehicle

Answer 1

Answer:

Average acceleration, $a=2.77\ m/s^2$

Explanation:

Given that,

Initial velocity, u = 0 km/h

Final velocity, v = 100 km/h = 27.77 m/s

Time, t = 10 s

We need to find the average acceleration of the vehicle. It is given by the change in velocity divided by time. Som,

$a=\dfrac{v-u}{t}\\\\a=\dfrac{27.77-0}{10}\\\\a=2.77\ m/s^2$

So, its average acceleration is $2.77\ m/s^2$.
