Because the velocity of an object depends on 7. as well as 8. the velocity of an object can change even as the 9. of the object remains constant. Imagine race cars going around an oval track. Even if their 10. remains constant, their velocity changes because the 11. of their motion is changing. If a car is traveling on a street and slows down, its speed 12. and the car has negative 13. Then the car speeds up, giving it positive 14. When the car was slowing down, the 15. was in the opposite 16. of the 17. To calculate a change in velocity, subtract the 18. from the If the direction of motion does not change and the object moves in a straight line, the change in velocity is the same as the change in 20. 19.​

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?

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
