1. The catapult on an aircraft carrier can take an aircraft weighing 300,000 N from 0 to 180 mph in 12.7 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.
2. An aircraft weighing 834 N is accelerated at 12 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 mass 371 kg is accelerated at 9.3 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?
