Our first goal is to measure and compare the angular momentum of the two-disk system before and after the small disk is dropped on the larger disk. Begin by measuring the angular speed of the large disk before the small disk is added. Calculate this initial angular momentum using the masses given above. Then, measure the angular speed of the two disks rotating together. Using this new velocity, calculate the final angular momentum of the two-disk system. Calculate the percent difference:

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue

Question 1 (5 pts): what is the maximum distance for which you can you resolve the two individual headlights of an on-coming truck as two separate lights rather than one if the headlights are separated by 2.00 m and your eye has a diameter of 1.00 centimeter? assume a wavelength of 500 nm.
