Question

A plane starting from rest (vo = 0 m/s) when t0 = 0s. The plane accelerates down the runway, and at 29 seconds, its velocity is +72.2 m/s. (+ indicates to the right). Determine the average acceleration for the plane.

Answer 1

Acceleration,
`a=2.48\ m/s^2`

Step-by-step explanation:

Given that,

The plane is at rest initially, u = 0

Final speed of the plane, v = 72.2 m/s

Time, t = 29 s

We need to find the average acceleration for the plane. It can be calculated as :

`a=(v-u)/(t)`

`a=(72.2)/(29)`

`a=2.48\ m/s^2`

So, the average acceleration for the plane is
`2.48\ m/s^2`. Hence, this is the required solution.
