AntidifferentiationTRANSCRIPT
Solution!
A.I.) Acceleration Take Off
a(t)1 = 2400v(t)1 = 2400t + C
I.) Acceleration:a(t)1 = 2400 km/h2
v(0)1 = 60 km/hs(0)1 = 10 km
< antidifferentiate a(t)1
*Starting with the acceleration section of the airplane's flight, we antidifferentiate the acceleration function using power rule.
A.I.) Acceleration Take Off
a(t)1 = 2400v(t)1 = 2400t + C60 = 2400(0) + C60 = C
I.) Acceleration:a(t)1 = 2400 km/h2
v(0)1 = 60 km/hs(0)1 = 10 km
< antidifferentiate a(t)1< input values of v(t)1 function
*Input the given values of the v(t)1 function to solve for the constant "C".
A.I.) Acceleration Take Off
a(t)1 = 2400v(t)1 = 2400t + C60 = 2400(0) + C60 = Cv(t)1 = 2400t + 60
I.) Acceleration:a(t)1 = 2400 km/h2
v(0)1 = 60 km/hs(0)1 = 10 km
< antidifferentiate a(t)1< input values of v(t)1 function
< substitute value "C" into v(t), to complete v(t)1 function
*Now that we have the v(t)1 function, our next step is to antidifferentiate this new function to find s(t)1.
A.I.) Acceleration Take Off
a(t)1 = 2400v(t)1 = 2400t + C60 = 2400(0) + C60 = Cv(t)1 = 2400t + 60
s(t)1 = 1200t2 + 60t + C
I.) Acceleration:a(t)1 = 2400 km/h2
v(0)1 = 60 km/hs(0)1 = 10 km
< antidifferentiate a(t)1< input values of v(t)1 function
< substitute value "C" into v(t), to complete v(t)1 function
< antidifferentiate v(t)1
A.I.) Acceleration Take Off
a(t)1 = 2400v(t)1 = 2400t + C60 = 2400(0) + C60 = Cv(t)1 = 2400t + 60
s(t)1 = 1200t2 + 60t + C10 = 1200(0)2 + 60(0) + C10 = C
I.) Acceleration:a(t)1 = 2400 km/h2
v(0)1 = 60 km/hs(0)1 = 10 km
< antidifferentiate a(t)1< input values of v(t)1 function
< substitute value "C" into v(t), to complete v(t)1 function
< antidifferentiate v(t)1 < input values of s(t)1 function
*Input the given values of the s(t)1 function to solve for the constant "C".
A.I.) Acceleration Take Off
a(t)1 = 2400v(t)1 = 2400t + C60 = 2400(0) + C60 = Cv(t)1 = 2400t + 60
s(t)1 = 1200t2 + 60t + C10 = 1200(0)2 + 60(0) + C10 = Cs(t)1 = 1200t2 + 60t +10
I.) Acceleration:a(t)1 = 2400 km/h2
v(0)1 = 60 km/hs(0)1 = 10 km
< antidifferentiate a(t)1< input values of v(t)1 function
< substitute value "C" into v(t), to complete v(t)1 function
< antidifferentiate v(t)1 < input values of s(t)1 function
< substitute value "C" into s(t)1, to complete s(t)1 function
A.II.) Constant Flight
v(t)2 = 660s(t)2 = 660t + C < antidifferentiate v(t)2
II.) Constant Flightv(t)2 = 660 km/h
s(0)2=30 km
*Next we work with the constant flight section of the airplane's flight. We antidifferentiate the velocity function using power rule.
A.II.) Constant Flight
v(t)2 = 660s(t)2 = 660t + C30 = 660(0) + C30 = C
< antidifferentiate v(t)2< input values of s(t)2 function
II.) Constant Flightv(t)2 = 660 km/h
s(0)2=30 km
*Input the given values of the s(t)2 function to solve for the constant "C".
A.II.) Constant Flight
v(t)2 = 660s(t)2 = 660t + C30 = 660(0) + C30 = Cs(t)2 = 660t + 30
< antidifferentiate v(t)2< input values of s(t)2 function
< substitute value "C" into s(t)2, to complete s(t)2 function
II.) Constant Flightv(t)2 = 660 km/h
s(0)2=30 km
*Now that we have the s(t)2 function for this section of the flight, we can move onto our final section.
A.III.) Deceleration Landing
a(t)3 = 840v(t)3 = 840t + C< antidifferentiate a(t)3
III.) Decceleration:a(t)3 = 840 km/h2
v(0)3 = 100 km/hs(0)3 = 583 km
*With our final section of the piecewise function, we antidifferentiate a(t)3 using power rule.
A.III.) Deceleration Landing
a(t)3 = 840v(t)3 = 840t + C100 = 840(0) + C100 = C
< antidifferentiate a(t)3< input values of v(t)3 function
III.) Decceleration:a(t)3 = 840 km/h2
v(0)3 = 100 km/hs(0)3 = 583 km
*We input the given values of the v(t)3 function to solve for the constant "C".
A.III.) Deceleration Landing
a(t)3 = 840v(t)3 = 840t + C100 = 840(0) + C100 = Cv(t)3 = 840t 100
< antidifferentiate a(t)3< input values of v(t)3 function
< substitute value "C" into v(t)3, to complete v(t)3 function
III.) Decceleration:a(t)3 = 840 km/h2
v(0)3 = 100 km/hs(0)3 = 583 km
*Now that we have the v(t)3 function, we continue by antidifferentiation to find the s(t)3 function.
A.III.) Deceleration Landing
a(t)3 = 840v(t)3 = 840t + C100 = 840(0) + C100 = Cv(t)3 = 840t 100
s(t)3 = 420t2 100t + C
< antidifferentiate a(t)3< input values of v(t)3 function
< substitute value "C" into v(t)3, to complete v(t)3 function
III.) Decceleration:a(t)3 = 840 km/h2
v(0)3 = 100 km/hs(0)3 = 583 km
< antidifferentiate v(t)3
*Simply antidifferentiate again using power rule
A.III.) Deceleration Landing
a(t)3 = 840v(t)3 = 840t + C100 = 840(0) + C100 = Cv(t)3 = 840t 100
s(t)3 = 420t2 100t + C583 = 420(0)2 100(0) + C583 = C
< antidifferentiate a(t)3< input values of v(t)3 function
< substitute value "C" into v(t)3, to complete v(t)3 function
III.) Decceleration:a(t)3 = 840 km/h2

< antidifferentiate v(t)3< input values of s(t)3 function
*Input given coordinate of s(t)3 to solve for the constant "C".
A.III.) Deceleration Landing
a(t)3 = 840v(t)3 = 840t + C100 = 840(0) + C100 = Cv(t)3 = 840t 100
s(t)3 = 420t2 100t + C583 = 420(0)2 100(0) + C583 = Cs(t)3 = 420t2 100t + 583
< antidifferentiate a(t)3< input values of v(t)3 function
< substitute value "C" into v(t)3, to complete v(t)3 function
III.) Decceleration:a(t)3 = 840 km/h2
v(0)3 = 100 km/hs(0)3 = 583 km
< antidifferentiate v(t)3< input values of s(t)3 function
< substitute value "C" into s(t)3, to complete s(t)3 function
s(t)1 = 1200t2 + 60t +10s(t)2 = 660t + 30s(t)3 = 420t2 100t + 583
*These three functions combine in their respective interval to depict the distance travelled over time by the airplane.
With this set of functions, we can move onto the next part and apply them.
A.) Conclusion

Take Off:s(t)1 = 1200t2 + 60t +10 < take off distance function
*Since the times required for take off and landing are the same between each citycity flight, we need to find these distances so that we can find the amount of distance flown at constant flight speed.
