Exercice 1 :
Pierre conduit une voiture à vitesse constante sur une portion
d’autoroute rectiligne.
Il parcourt 450 m pendant une durée égale à 9500 ms. Puis, à
la même vitesse, il aborde un virage en arc de cercle.
1. Calculer la vitesse de Pierre dans :
a) Le référentiel lié à la voiture.
b) Le référentiel lié à la route.
2. Quelle est la trajectoire de Pierre dans le référentiel lié à la
route ?
3. En déduire la nature du mouvement de Pierre dans ce
même référentiel.

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?

Organelles are 1. responsible for producing power for the cell 2. tiny structures in the cell that carry out the cell's activities 3. responsible for digestion in the cell 4. found outside of the membrane
