Pre laboratory Assignment Due at the beginning ofyour lab class. Answer all questions. Only some will be graded, for a total of 10 points. Ultra-sonicmotion In experiments 1 and 2, you will use a cart, track, Pulley _ ' sensor and motion detector like those illustrated in / smug mm" y'amemraumper \\'l Dataacqmsmon Figure 1 to explore the relationships between . ,',,,,,,,T,r,a,'71? ,,,,,,, \\D: II PC the force acting on an object, the mass of that gel\" H / i." object and its acceleration. ~Levelingjacks /' Figure 1. Experimental setup Consider the following exercises / questions relevant to Parts 1 and 2. 1. Use the diagram to the right to draw all forces (arrows that represent these vectors) acting on each object in the system you are going to investigate. Here, a force T(tension) is applied to the cart of mass mcam by means of a string with an attached mass mw. All forces should extend away from the object in the direction of the force. Remember that the length of the arrow is an indication mw ofthe magnitude ofthe force. 2. Write Newton's 2nd Law (2 F" = mc'i) in component form (2 Fx = max and 2 F3, = may. here mis either mm,r or mw) for each object in the system (cart and mass attached to the string). 3. How is friction compensated for in this experiment
