How long does it take for an airplane to change its velocity from 140 m/s to 180 m/s if its acceleration is 4.0 m/s?? How far does it travel during this time? (10. s, 1600 m)
Proof please

Explanation:

a = 4ms⁻²,  Vf = 180 m/s  &  Vi = 140m/s

a =

4 =

t = 40/4

t = 10sec

To Measure Distance Use third Equation of Motion:

2aS = Vf²-Vi²

S =

S = 12800/8 = 1600m

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
