parameters and run the simulation a couple of times. Analysis and Questions: 1. Set the parameters as follows: vo = 0, k = 0.4000, s = 0.5000, g = 9.810 m/s2, m = 5.000 kg. Predict: In order to keep the block at rest on the incline plane, the angle of the incline plane  can’t exceed what value? Draw a free body diagram of the block and show your calculation. 2. Set the angle  to your predicted value (keep proper significant figures otherwise it will affect your simulation result). Does the simulation result match your prediction? If it doesn’t, redo your calculation and modify your answer to question 1. Keep testing until the simulation result matches your prediction. 3. Will increase or decrease the mass of the block affect your prediction to question 1? Explain.
Please don't use ai to answer I will report your answer please solve it with proper calculation and explanation......... Here is figure (c) from example 3-8
L no frictin M 4) In the diagram above, an isolated charged parallel-plate capacitor holding charge Q is arranged horizontally, with one plate flush with a frictionless surface. The capacitor has capacitance Co when there is no dielectric inserted. The dielectric block (mass m, dielectric constant k) inside the capacitor is attached to a hanging block (mass M) by a massless string routed over a frictionless pulley. The length of the capacitor plates and dielectric block is L along the direction of motion. Assume there is no friction between the dielectric and the capacitor plates. a. The blocks are initially at rest and the dielectric is initially completely inside the capacitor. Use conservation of mechanical energy to determine the speed v of the falling block at the moment the dielectric block completely exits the capacitor plates (in other words, determine a formula for the speed in terms of the various parameters that have been defined as algebraic variables).
Solve the following problem and show your complete solutions. Explain your work for better understanding. And illustrate the FBD
Each of the images below represents a plot. The horizontal axis on each plot represents time. The vertical axis represents whichever quantity (position, velocity, acceleration) is being discussed. The origin of each plot is represented by 0, and the function is represented by the colored line. For each of the statements at the bottom select the image that best represents the requested plot. You may use the same image for multiple statements if it is appropriate. B A k TEKK AA car starts from rest at a stoplight and undergoes constant acceleration to the East. Which graph best represents the velocity of the car as a function of time? (Choose East to be the positive direction.) H You hold your arm out over a cliff and release a ball from rest. Consider the time from just after the ball leaves your hand to just before it hits the ground. Which graph best represents the position of the ball as a function of time?

A car drives around an eliptical race track as pictured at right. It starts at rest near the bottom of the diagram and speeds up to its maximum speed between points A and B, after which it conintues at a constant speed. Draw acceleration vectors at points A, B, and C to represent the direction of the acceleration of the car at these 3 points. Explain your answer. Is the magnitude of the acceleration at point B larger, smaller, or equal to the magnitude of the acceleration at point C? Explain your answer.
