An airplane traveling 245 m/s east experienced turbulence, so the pilot decided to slow down to 230 m/s. it took the pilot 7 seconds to get down to this speed. what is the acceleration of the plane? (round your answer to the nearest integer.) a.–2 m/s2 b. 2 m/s2 c. 67 m/s2 d.–67 m/s2

Use the formula for acceleration:

a = Δv ÷ Δt

This is the same as:

a = ( v₂-v₁ ) ÷ Δt

Substitute values into equation and solve.

a = (230 m/s [E] - 245 m/s [E] ) ÷ 7 s

a = -15 m/s [E] ÷ 7 s

a = -2.1428 m/s² [E]

Therefore the acceleration of the plane is -2 m/s² [E].

A.–2 m/s2

Explanation:

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.
