PROBLEMS: Solve the following problems and show your work in the space provided. (Don't forget to label your answer with the proper units.)

1. 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.)

2. 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.

3. A 9,600 lb airplane takes off at 160 ft/sec. If it accelerates at a constant rate of 30 ft/sec2:
1. How much time is needed to reach takeoff speed?
2. What is the length of the airstrip?
3. What force is needed to produce this acceleration?

4. 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?
