$Y:\How to solve 2 dimension relative velocity problems.wpd$

Part 1 Part 2Attached Force (N) AccelerationMass of CartMass (kg)(m/s 2 )(kg)Acceleration(m/s 2 )When you have collected the data for all experiments, minimize the MPLI program and enterGraphical Analysis.→ Plot the data for each experiment. An acceleration vs. Force graph (for Part 1) andacceleration vs. mass of cart graph (for Part 2) should be obtained.→ Remember to use the curve fitting options to obtain a line of best fit for each graph.Analysis:1. State the proportionalities for both graphs and the joint variation proportionality.2. Determine the average proportionality constant for the joint variation (see Appendix J).What are its units?3. Rewrite the equation for this data.a. Solving for acceleration.b. Solving for force.- 30 -
4. According to 3b what are the units of force? Are these units equivalent to the newton?5. Based on the units given in question 4, describe in your own words what 1N of net forceis.6. Imagine a massless object under the influence of some net force. How much accelerationdoes it have? [By massless we are referring to an object that is so small that it can beconsidered massless but does not have a mass of zero.]7. A student told me that an object’s mass is its resistance to being in motion, ( i.e.,massive objects come to a stop faster than lighter objects). Is this idea correct? Defendyour choice in terms of the graphs you have plotted.8. State two ways to calculate net force.9. Given this scale VCD and that the object has a mass of 2.50 kg, what is its acceleration?How far will the object travel in 5 seconds, if it starts from rest?F N1 cm = 1 NF mF rF g sin θF g cos θ- 31 -
