PROBLEMS: Solve the following problems and show your
work in the space provided. (Don't forget to label your answer with
the proper units.)
 An airplane begins its takeoff run at a speed of 40 knots. If
the runway is 6,000 ft long and it takes 20 seconds to reach
liftoff speed, what acceleration must the pilot maintain for
takeoff? (One Knot=1.69 ft/sec)
 An 8,200 kg airplane touched its runway at 65 m/s and came to
a stop in 25 seconds.
Find (A) negative acceleration and (B) the length of the runway.
 A 9,600 lb airplane takes off at 160 ft/sec. If it accelerates
at a constant rate of 30 ft/sec^{2}:
 How much time is needed to reach takeoff speed?
 What is the length of the airstrip?
 What force is needed to produce this acceleration?
 A military airplane flying at a speed of 350 m/s must make a
supply drop. The pilot releases the supply crate 2,400 m before
the drop target. How long will it take for the crate to hit the
ground?
