The diagram below shows the rectangle boar find the length of line pa if entering your answer as a decimal

motionless puck as shown on the picture above. The net force that the stick applies on the puck is 150N and the contact lasts for 7.5 ms. The mass of the puck is 166 g. A) (1 point) Calculate the acceleration of the puck under the influence of the net force. B) (2 points) Calculate the puck's change in momentum due to the impulse applied by the hockey stick. C) (1 point) What is the velocity of the puck once it leaves the stick? Puck travels over rough ice and comes to a stop after 25 m. The force diagram below shows all forces acting on the puck during that travel. Screen Shot 2020-11-02 at 2.04.05 PM.png D) (1 point) Calculate the work done on the puck by gravitational force. E) (1 point) Calculate the work done on the puck by normal force. F) (2 points) Calculate work done by friction force on the puck. CNX_UPhysics_09_03_HockeyPuck.jpg Now stationary, the puck (red) collides with a blue puck of the mass .332 kg moving to the left with velocity of 2.5 m/s. If collision is perfectly elastic calculate: H) (2 points) Total momentum of blue+red puck system before collision? I) (1 point) What is the total momentum of blue+red puck system after collision? How do you know? J) (2 points) What is the velocity of the blue puck after collision?

decimal. Round your final answer to the nearest hundredth.

va for a class, including attributes, accessors, mutators, and constructors. Design and write Java for an application program that instantiates and uses objects of a user-defined class. Use the repetition structure in class methods and application program modules. Perform error checking. Use a graphical drawing program (ArgoUML) to create class diagrams. Directions for completing and submitting the homework: You will be submitting the following files: Task #1: Pseudocode written with Word, Notepad++, or similar application Task #2: Pennies.java Task #3 Inventory.java The application class created in 3b below The UML class diagram created in ArgoUML, Raptor, or similar application Homework Assignment: Write the pseudocode needed to complete Chapter 5, number 9 – Pennies for Pay. Implement Pennies for Pay in Java. The Secondhand Rose Resale Shop is having a seven-day sale during which the price of any unsold item drops 10 percent each day. Design a class diagram showing the class, the application program, the relationship between the two, and multiplicity. Then write the Java code as described below. Be sure to follow the CSI 117 Style Criteria (Links to an external site.) for naming conventions, class diagrams, pseudocode, keywords, and operators. An Inventory class that contains: an item number and the original price of the item. Include the following: A default constructor that initializes each attribute to some reasonable default value for a non-existent inventory item. Another constructor method that has a parameter for each data member, called the overloaded constructor. This constructor initializes each attribute to the value provided when an object of this type is instantiated. Be sure to incorporate adequate error checking for all numeric attributes. Accessor and mutator methods for each attribute. Be sure to incorporate adequate error checking for all numeric attributes. Extra credit for including Javadoc comments. An application program that contains two methods: the main() module and the printSaleData()module. The main()module must do the following: create an Inventory object using the default constructor use a loop to get inventory items from the user. The user should enter the item number and the original price of the item. This loop should continue until the user indicates that they have no more items to enter. For each item entered by the user, the code inside the loop should do the following 2 items: set the attributes of the Inventory object by calling the appropriate method in the Inventory class for each item entered by the user send the Inventory items, one at a time, to the printSaleData() module for processing Extra credit for including Javadoc comments. The printSaleData()module must accept an Inventory object and produce a report that shows the item number and the price of an inventory item on each day of the sale, one through seven, using a loop. For example, an item with an original price of $10.00 costs 10 percent less, or $9.00, on the first day of the sale. On the second day of the sale, the same item is 10 percent less than $9.00, or $8.10.
