15. The minimum stopping distance for a car traveling at a speed of 30 m/s is 60 m, which includes the distance traveled during the driver's reaction time of 0.50 s. Assuming that the car was at $x_i = 0$ when the driver first saw the emergency that called for a rapid stop, draw a position-versus-time graph for the car. What is the minimum stopping distance for the same car traveling at a speed of 40 m/s?

1. A unity feedback system has a forward T.F KG = K \frac{s^2+3s+2}{s^2+2s+2} Calculate the angles of departure from the pole at -1+j 2. A unity feedback with KG= \frac{K}{s(s+3)(s+8)} operates with %OS=30% and \omega_n= 2.62 rad/sec. a. Use rlocus to find the gain, K, at the operating point b. A PD controller Kc(s+z) so that the settling time is one third that of the uncompensated system. Find z c. Use rlocus to fin the new gain, K, and plot the step response for both systems

Purpose: To practice your ability to create and manipulate lists. Degree of Difficulty: Easy Pokemon are fantastic creatures that people like to catch and train. For this question, you will write a program that allows the user to keep track of the Pokemon they have caught, and then assemble a team from among the Pokemon caught that can be taken to the local Pokemon Gym for training. Your program will have two phases. When the program first starts, it should repeatedly show a prompt to the user asking if they want to catch another Pokemon. Each time they say yes, the program should ask the user to enter the name of the Pokemon that was caught and it should be added to a list variable that holds the user's complete Pokemon collection. When they say no, the program should continue to the second phase. Get this part of the program working before going any further. Do not move on to the second part of the program until you know that the first part works. In the second phase, the program will display the current Pokemon collection, as well as a list of Pokemon that have been added to the user's Gym Team (initially, this second list will be empty). A prompt will then ask the user to name the Pokemon from their collection that they would like to add to the Gym Team. The Pokemon entered should be removed from the first list (the Pokemon collection) and added to the Gym Team list. This process should continue until EITHER (a) there are 6 Pokemon on the Gym Team, or (b) all of the Pokemon from the collection have already been added to the Gym Team.
