-Consider an object that moves only along the positive X axis that is subjected to a constant force pointing in the positive X direction. Show the work done by this force is the area under a Force vs. Displacement plot. (I wrote this question exactly as it was given)
-A cart has a of mass (851.8±0.1)g. The tension in the string is 0.36N and the cart has a displacement of 40.9cm. Determine the work done by tension.
-The cart in the previous example has a maximum velocity of (0.580±0.017)m/s. Determine the kinetic energy of the cart and compare the result with the work done on the cart in Problem 2 to confirm the Work-Energy Theorem.
