A 0.40 kg cart with charge of +4.0 x 10-8 C starts at rest on a horizontal frictionless surface 0.50 m from a fixed object with charge +2.0 x 10-8 C. When the cart is released, it moves away from the fixed object. A sketch of the physical situation with all given physical quantities clearly labeled. If the description above consists of an initial and final state, both of these states should be represented in your sketch. Draw an energy bar chart to represent the energy representing the changes in the energy in a system consisting of the fixed object and cart throughout this process. Determine the velocity of the cart when it is 2.0 m from the fixed object. Show all work and explain your thought process in words. Your explanation should cover both what you did and the thought process behind why you did that. Evaluate your answer to determine whether it is reasonable or not. Consider all aspects of your answer (the numerical value, sign, and units) in your evaluation.

If a force F = 200N is applied to the 30-kg cart, show that the 20-kg block A will slide on the cart. Also, determine the time for block A to move on the cart 1.5 m. The coefficients of static and kinetic friction between the block and the cart are 0.3 and 0.25. Both the cart and the block start from rest.

Consider a 200-kg cart starting from rest at point A, which is 6.0m above the ground as shown in the figure below. The cart follows the roller-coaster tracks from point A to point B, where point B is 3.2m above the ground. Assuming the potential energy of the system is zero at the ground level and rounding off the number to three significant figures, the speed of the cart at point B is m/s. If 3 kJ of the total mechanical energy is lost due to friction between points A and B, the speed of the cart at point B is m/s.
