A plane speeds up from 30 m/s to 52 m/s in 4 seconds. What is its acceleration?

Expert Solution

The change in velocity is just the difference in the two velocities. So the difference between 12 m/s and 25 m/s can be calculated as:

52 m/s -30 m/s = 22 m/s

-This means that the car used an unknown acceleration to increase its velocity by 22 m/s.

-Acceleration is calculated by the formula: a_av = Dv/Dt, so we can put the numbers in and get this:

a= (22/s) / (4sec)

Its acceleration is a= 5.5m/s/s
