Ou and your friend find yourselves in an unfortunate situation. a shopping-cart-related stunt has gone wrong and now your friend is stuck in a shopping cart and is on a crash course for your house with speed v= 2.15~\mathrm{m/s}v=2.15 m/s. you are on the roof of your house, which forms an angle \theta = 49.9^{\circ}θ=49.9 ∘ with the horizontal, and it's your job to stop your friend. you size up the situation and see that the mass of your friend and the cart combined is m = 45.7~\mathrm{kg}m=45.7 kg and luckily you have some camera equipment with you whose total mass is m = 36.0~\mathrm{kg}.m=36.0 kg. your plan is as follows. you're going to climb up the roof, place the equipment on the (frictionless) rooftoop, and let it slide off the roof, which is a height h=11.7~\mathrm{m}h=11.7 m above the ground. your friend is going to catch the equipment and get slowed down by it. how far up the roof do you need to climb in order for your friend to come a complete stop?

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?

Why can blue light and yellow light combine to produce white light? question 17 options: they are both primary colors of light. they absorb each other's wavelengths. because blue, yellow, and white are primary colors. they are complementary colors of light.
