Question

4. A vehicle

accelerates from
0 km/h to
100 km/h in 10 s.
What is its average
acceleration?

Answer 1

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

Step-by-step 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=(v-u)/(t)\\\\a=(27.77-0)/(10)\\\\a=2.77\ m/s^2`

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