1. An aircraft starts at rest and is accelerated at 11.1 m/s2 for 10.1 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. When an aircraft returns to the aircraft carrier and lands, it goes from 395 kilometers per hour (kph) to 0 kph in 2.9 seconds. What is the acceleration (in m/s2 )? CAUTION: Think about what is happening in a physical sense and that it matches your answer.
3. 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).
