 Measurement   Odd Tables:  Take the measurements necessary to determine the kinetic energy of the cart just before and after the impact with the bumper. Take data for several different initial heights. Analysis Calculate the efficiency of the bumper for the level track.  Does your result depend on the velocity of the cart before it hits the bumper? Conclusion What is the efficiency of the magnetic bumpers?  The efficiency was 90.68 +- 5.01%, it seemed that most trials were pretty high up there in efficiency with the lowest percentage being 89% which is not bad for the leveled track. The result does depend on the velocity of the cart since as the velocity increased the percentage went higher.    How much energy is dissipated in an impact? State your results in the most general terms supported by your analysis. Is the effect of friction significant? The average energy dissipated across all trials is 7.557 × 10^−4 J using the initial and final velocities...

  1. For each new block mass, calculate the magnitude of the kinetic frictional force from the measured t.  Also determine the normal force on the block. 2. Graph the magnitude of the kinetic frictional force against the magnitude of the normal force, for a constant angle of incline.  On the same graph, show your predicted relationship. 3. For each angle (h), calculate the magnitude of the kinetic frictional force from the measured t.  Also determine the normal force on the block. 4. Graph the magnitude of the kinetic frictional force against the magnitude of the normal force for a constant block mass.  On the same graph, show your predicted relationship. 5. Calculate the uncertainty in your experimental technique.   Do your two graphs agree? My two graphs do not agree, i don't know what happened with the second graph Conclusion:  What is the coefficient of kinetic friction for wood on aluminum?  How does this compare to y...
