How high will a ball of mass 2 kg thrown with velocity 4 m/s straight up travel before it starts to fall down again? How far will an object of mass 2 kg sliding on a surface with initial velocity 4 m/s travel before it comes to a complete stop, if it experiences a constant friction force of 2 N? If the object in the previous question were to travel twice as fast initially, how much further would it travel before it came to rest? A. It would go 1.4 times as far. B. It would travel the same distance. C. It would travel 4 times as far. D. It would go twice as far.

Why don't you see your reflection in water with waves or repples

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?
