Ajetliner rolls down the runway with constant acceleration from rest, it reaches its take off speed of 250 km/h in 1 min. what is its acceleration? express in km/h^2, does this result make sense?

Acceleration,

Explanation:

Given that,

Initially, the jetliner is at rest, u = 0

Final speed of the jetliner, v = 250 km/h

Time taken, t = 1 min = 0.0167 h

We need to find the acceleration of the jetliner. The mathematical expression for the acceleration is given by :

So, the acceleration of the jetliner is . Hence, this is the required solution.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
