Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

You were leisurely flying your F-18 when you encounter an alien aircraft. The alien was flying at an
altitude of 3 km while you were at an altitude of 600 m. You begin to increase your speed at a rate of
2.0 m/s?. You are traveling at a speed of 750 km/h at the instant when O = 45° and at the same instant
the alien has a constant velocity of 1,500 km/h.
a) Determine the velocity and acceleration vectors (in m/s and m/s², respectively) of the alien as
observed by you. [Ans. to Check: V8/a = 208.4 į m/s]
b) Determine the time rate of change of the vector r that is between you and the alien ship in m/s.
In other words, find ř. [Ans. to Check: † = 147.32 m/s] Hint: Do not forget about your ability to dot
in different directions to eliminate variables from the equation.
c) Calculate the angular velocity of the spaceship relative to you in rad/s.
d) Determine the radial and angular accelerations in m/s² and rad/s². [Ans. to Check: * = 4.86 m/s²]

How should the kinematic diagrams look for these two problems?
During the middle of a family picnic, Barry Allen received a message that his friends Bruce and Hal needed to be saved. Barry promised his wife Iris that he would be back in exactly 5 minutes. From that that picnic location, Barry runs at a speed of 600 m/s for 2 minutes at a heading of 35° north of west to save Bruce. He then changed his heading to 30° west of north, slows down to 400 m/s and runs for 1 minute to save Hal. (The changes in speed are essentially instantaneous and not part of solving this problem).(a) Draw a physical representation of the displacement during Barry’s full trip.(b) Use the Related Quantities sense-making technique to compare Barry’s total distance traveled to themagnitude of his displacement.(c) What average velocity (magnitude and direction) does Barry need to return back to the picnic inorder to keep his promise to Iris?
