Motion – Newton’s Laws
Total mass at liftoff:
2040000 Kg
Total thrust:
31000000 N
What is the
acceleration of the
vehicle at liftoff?
F = ma or a = F/m
a = 31000000 N / 2040000 Kg = 15.2 m/s2

Motion – Newton’s Laws
Note:
ashuttle = 15.2 m/s2
For the Bugatti Veyron (the fastest
accelerating production car ever built):
aVeyron = 11.1 m/s2
For a Formula 1 car:
aF1 = 14.2 m/s2

FThrust
Thrust (in N)
W
Weight (in N)
Fnet = Fthrust - W
Motion – Newton’s Laws
Fnet
=
Fthrust – W
=
Fthrust – mg
=
31000000 N – (2040000 Kg) ( 9.8 m/s2)
=
11008000 N

Motion – Newton’s Laws
a
=
Fnet / m
=
11008000 N / 2040000 Kg
=
5.396 m/s2 = 0.5506 g
