1. An aircraft starts at rest and is accelerated at 11.1 m/s2for 12.8 seconds, at which time the aircraft launches. What is the distance traveled from the starting point to the launch point? Assume the acceleration is constant.
2. An aircraft weighing 937 N is accelerated at 9 m/s/s for 9 seconds, at which time the aircraft launches. How much work was done on the aircraft? The acceleration is constant.
Hint: This is a multiple step problem in which you must derive the variables needed (mass and distance under constant acceleration) in step one and then apply those values to the final solution of the problem in step two, that is calculate the work done.
3. An aircraft with a weight of 9724 N accelerates from 0 to 82 m/s in 9.4 seconds, at which time the aircraft launches. What is the kinetic energy of the aircraft when the aircraft launches?
4. A 196.2 kg satellite is in a circular orbit of 22,000 miles (35,405,000 m) in radius. The force keeping the satellite in orbit is 48.9 N. What is the velocity (speed) of the satellite?
5. An aircraft with a mass 275 kg is accelerated at 10.1 m/s2 for 5 seconds, at which time the aircraft launches. Assume the acceleration is constant. What is the force required to launch the aircraft?
6. The catapult on an aircraft carrier can take an aircraft from 0 to 215 mph in 5 seconds, at which time the aircraft launches. Express the launch speed in SI units (meter-kilogram-second (MKS) system - not km/hr).
7. The catapult on an aircraft carrier can take an aircraft weighing 300,000 N from 0 to 188.8 mph in 10.4 seconds, at which time the aircraft launches. What is the acceleration of the aircraft when it launches? Express your answer in the MKS system of units.
8. A pilot will black out if experiencing a centripetal acceleration of greater than 5g's. An F-16 going 319 mph enters a tight turn of radius 396 m. The pilot in this case is experiencing how many g's? You do not need to enter units for this problem.
9. You find a 30 N box on the middle of a set of stairs and carry the box up a flight of stairs to a deck, raising its elevation by 5 m. Then you drop the box off of the deck. As the box reaches its original level (the box is moving when it reaches the original level because it has not reached the ground), its kinetic energy is
