Sarah wanted to know the velocity of an airplane traveling from houston to dallas. after recording the distance (in miles) and time (in hours) it took to travel to dallas, what other measurement does sarah need to determine the airplanes velocity? a) acceleration b) direction c) force d) inertia

Option B is the correct answer.

Explanation:

 Velocity of a body = Displacement of the body/Time taken

Displacement and velocity are a vector. Both have direction and magnitude.

Displacement is generally distance with direction.

If we divide distance with time taken we will get speed of the airplane. Speed with direction is called velocity. So we need distance between Houston and Dallas, time taken by plane to travel from Houston to Dallas and direction of displacement from Houston to Dallas.

So we need direction.

Option B is the correct answer.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
