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

Answer:

Explanation:

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

a = [tex]\frac{Vf-Vi}{t}[/tex]

4 = [tex]\frac{180-140}{t}[/tex]

t = 40/4

t = 10sec

To Measure Distance Use third Equation of Motion:

2aS = Vf²-Vi²

S = [tex]\frac{180*180 - 140*140}{2(4)}[/tex]

S = 12800/8 = 1600m
