14) Three identical 5 kg crates are stacked one on top of the other. You want...
mi m2 Two wooden crates rest on top of one another. The smaller top crate has a mass of my = 24 kg and the larger bottom crate has a mass of m2 = 87 kg. There is NO friction between the crate and the floor, but the coefficient of static friction between the two crates is Hs = 0.82 and the coefficient of kinetic friction between the two crates is Mk = 0.64. A massless rope is attached to...
I need the answer for #5 only m m2 Two wooden crates rest on top of one another. The smaller top crate has a mass of my = 24 kg and the larger bottom crate has a mass of m2 = 87 kg. There is NO friction between the crate and the floor, but the coefficient of static friction between the two crates is Hs = 0.82 and the coefficient of kinetic friction between the two crates is Mk =...
Parts D and E only please A 5 kg block is sliding at an initial speed of 9 m/s across a surface, encountering a constant friction force of 6 N. How much work is done on the block after it slides 22 cm? rrect, computer gets: -1.32 J int: Does the block gain or lose energy during this process? What sign does this imply for the work done on it? How fast is the block moving after sliding 22 cm?...
Could you please help with question 5 and 1 NOTE: the answer for question 5 is NOT 112mm, 224mm, 37.33mm NOTE: the answer for question 1 in NOT FTFTF, FTTTT, FTFTT, FTTTF 5. [1pt] Four identical books of mass 790 g and width a = 224 mm are stepped equally and so as to maximize the overhang, d. Calculate d.

Dr. C. #2. (PHYS 121 engineering design exercise) You have seen why cars inherently accelerate quicker in a straight line and have better fuel mileage than an SUV with the same engine; it's because of air drag and the smaller frontal area and better drag coefficient of the car. Now let's think about why cars handle (take turns, change lanes and make other quick maneuvers) better than an SUV. We'l1 simplify our analysis by considering a vehicle of mass M...
