An airplane with a mass of 10,000kg is rolling down a runway and experiences an unbalanced upward
force of 20,000N. Because of this, the airplane must be
(A) accelerating down the runway at 2m/s
.
(B) taking off with an upward acceleration of 2m/s.
(C) accelerating down the runway at 0.5m/s
(D) taking off with an upward acceleration of 0.5m/s.
An airplane with a mass of 10,000kg is rolling down a runway and experiences an unbalanced upward
force of 20,000N. Because of this, the airplane must be
(A) accelerating down the runway at 2 m/s.
No. An upward force component yields
an upward acceleration component.
An airplane with a mass of 10,000kg is rolling down a runway and experiences an unbalanced upward
force of 20,000N. Because of this, the airplane must be
(B) taking off with an initial upward acceleration of 2m/s.
Yes. a = F/m = (20,000/10,000) m/s.
An airplane with a mass of 10,000kg is rolling down a runway and experiences an unbalanced upward
force of 20,000N. Because of this, the airplane must be
(C) accelerating down the runway at 0.5m/s
No. An upward force component yields
an upward acceleration component a = F/m.
An airplane with a mass of 10,000kg is rolling down a runway and experiences an unbalanced upward
force of 20,000N. Because of this, the airplane must be
(D) taking off with an upward acceleration of 0.5m/s.
No. Divide the force component by the mass: a=F/m=(20,000/10,000) m/s
