1. An aircraft weighing 991 N is accelerated at 11 m/s2 for?13 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.
2. When an aircraft returns to the aircraft carrier and lands, it goes from 242.4 mph to 0 mph in 3.1 seconds. What is the acceleration in this case? CAUTION: Think about what is happening in a physical sense and that it matches your answer.
