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?
4. A 0.11 kg bullet traveling at 1565 mph hits a 6.3 kg block of wood and stays in the wood. What is the velocity (speed) of the wood block immediately after the bullet hits it?
5. An aircraft with a weight of 8387 N accelerates from 0 to 100 m/s in 7.9 seconds, at which time the aircraft launches. What is the kinetic energy of the aircraft when the aircraft launches?
6. It takes an elevator 2.6 minutes to raise a vehicle with a weight of 4161 N from the floor to a height of 6 meters. What size (power) motor (in watts) does it take to do the job? Hint: this is a multiple step problem in which you must derive the variables needed to solve for problem in step one and then apply those values to the final solution of the problem.
7. 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.
8. 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.
9. The catapult on an aircraft carrier can take an aircraft from 0 to 215 mph in 5 seconds, at which timethe aircraft launches. Express the launch speed in SI units (meter-kilogram-second (MKS) system - not km/hr).
10. A 215.3 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 49.2 N. What is the velocity (speed) of the satellite?

Why a risk-averse person might buy unfair insurance
: By one estimate, fan loyalty cost U.S. employers as much as $627 million (Josie Roberts, Pittsburgh Tribune-Review, May 19, 2005). Is this productivity loss an example of a negative externality? Explain.
