10) A solid disk with a c of 1/2, mass of 2 kg, and radius of 1.4 meters lies on a horizontally (so the normal force and weight can be ignored). A force of 9 Newtons is applied 0.37 meters directly to the right of center in the +x direction, a force of 25 Newtons is applied 0.80 meters directly below of center in the +x direction, and a force of 9 Newtons is applied at the edge of the disk directly above the center in the +x direction. Again, ignoring the weight and normal force, if the disk starts from rest, what is the angular velocity of the disk after these forces are applied for 3 seconds, in rad/s? If clockwise, include a negative sign.

(1) An air track that is 2 meters long is raised by 2 cm on one end. What vertical distance does an air cart move if the air cart moves from the 1 meter mark to the 2 meter mark? 1 cm

(2) If the above air cart starts from rest, what would you expect its velocity to be 0.5 meters along the air track? Use the equations of conservation of energy. Assume the air track is frictionless.

(3) Is the result of Question (2) consistent with what you would expect based on the equations of kinematics? Solve for the expected velocity based on the equations of kinematics and compare.

Write a program that uses nested loops to collect data and calculate the average rainfall over a period of years. The program should first ask the user for the number of years. The outer loop will iterate once for each year. The inner loop will iterate 12 times, once for each month. Each iteration of the inner loop will ask the user for the inches of rainfall for that month.

After all iterations, the ­­program should display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.

Add additional loops to validate the input:

• Do not accept a number less than 1 for the number of years. Continue to prompt the user for a number until a valid number is entered.
• Do not accept negative numbers for the monthly rainfall. Continue to prompt the user for a number until a valid number is entered
