Question
A Boeing 747 airliner which weighs 802,000 lb taxis down a runway and
reaches a velocity of 75.0 mi/h. The airplane starts from rest, and its engines
can deliver 175,000 lb of thrust.
(a) Find the plane's mass.
(b) Find its momentum.
(c) Find its change in momentum.
(d) In order to reach this velocity, what impulse was delivered to the plane?
(e) How long did the plane take to reach its speed? (Assume that the thrust of
the engines remains constant and ignore air resistance.)
