C++ When an object is falling because of gravity, the following formula can be used to determine the distance that object falls in a specific time period: d = 1/2 g t*t The variables in the formula are as follows: d is the distance in meters g is 9.8 t is the amount of time, in seconds that the object has been falling. Design a function called fallingDistance() that accepts an object's falling time (in seconds) as an argument. The function should return the distance, in meters, that the object has fallen during that time interval. Design a program that calls the function in a loop that passes the values 1 through 10 as arguments and displays the return value. 5 Falling Distance (5 points) Seconds Meters 1.0 4.9 2.0 19.6 3.0 44.1 4.0 78.4 5.0 122.5 6.0 176.4 7.0 240.10000000000002 8.0 313.6 9.0 396.90000000000003 10.0 490.0

1. Horizontal force needed to keep a sled moving along dry (it means not wet) horizontal surface is 10 N. You increase this force up to 20 N. Neglect air resistance.  What can you say about character of motion of a sled now?

a. Sled will continue to move with the same speed.

b. Sled will accelerate for a while up to higher speed and then move with constant, higher speed.

c. Sled will accelerate indefinitely.

d. Sled will move with constant speed two times greater than initial.

a. Less than two times

b. Exactly twice

c. More than twice

Now we will analyze the truck and load as two individual objects that interact with each other as they accelerateleft:2)We’ll start with analyzing the load.a.You discuss what forces are acting on the load with some fellow students. Everyone agrees that the Earth exerts a downward force on the load, but there is some disagreement about any other forces acting on the load. Use⃑as the force which the truck exerts on the load. The vertical component of ⃑is often given a specific name. If the load is simply resting in the bed of the truck (not tied down or in contact with the gate at the back of the bed), then the horizontal component of ⃑is also given a specific name. What are these names, and which way do the two components point (up or down; and left or right? Below, you can refer to the components of ⃑with the names you noted here if you would like to do so.

b. Draw a free body diagram for the load (using the same coordinate system that you used above).

c. Use Newton’s first two laws to determine the vertical and horizontal components of ⃑in terms of F drive, MT, mL, and g. (If one is zero, explicitly state that it is. Refer back to some of your conclusions from Question 1 about the acceleration of the load.)

Instructions: program in C++, add pseudocode and comment throughout the program.

Assignment:

Create a program to keep track of the statistics for a kid’s soccer team. The program will have a structure that defines what data the program will collect for each of the players.

The structure will keep the following data:

• Players Name (string)
• Players Jersey Number (integer)
• Points scored by Player (integer)

The program will have an array of 12 players (use less for testing and development, use a constant for the size). Each element in the array is a different player on the team.

The program will ask the user to enter information for each player. The program will also display the team information in a table format. After the table, the total points scored by a team will be displayed.

The program will also determine which player scored the most points on the team.

Validation:

• Do not accept negative value for player’s number
• Do not accept negative value for player’s score

Required Methods:

• void GetPlayerInfo(Player &);
• void ShowPlayerInfo(const Player);
• int GetTotalPoints(const Player[ ], int);
• void ShowHighest(Player [ ], int);

The job market of the 21st century is often referred to as the “gig economy.” Employers such as Uber, Amazon, Airbnb, and others are increasingly relying on short-term freelance employees who work on a piecemeal basis.

Proponents of the gig economy suggest it offers workers the freedom to work where and when they want, while employers can reduce labor costs by avoiding health insurance and payroll taxes. Others suggest that businesses are simply taking advantage of a tough economy to cut benefits and offer lower wages to people desperate for work.

If you were the head of a large corporation, would you consider it ethical to profit from the gig economy?

Note that you need to validate all definitions, and matters not known as facts, by citing from credible sources.
