Concept explainers
For the given several questions, consider the dot diagram below for the motion of an object along a horizontal surface. The motion is divided into several time intervals, each labeled with a letter.
1. During which time interval(s), if any, are there no forces acting upon the object? List all that apply.
2. During which time interval(s), if any, are the forces acting upon the object balanced? List all that apply.
3. During which time interval(s), if any, is there a net force acting upon the object? List all that apply.
4. During which time interval(s), if any, is the net force acting upon the object directed toward the right? List all that apply.
5. During which time interval(s), if any, is the net force acting upon the object directed toward the left? List all that apply.

- 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.arrow_forwardProblem 1: A book is resting on a frictionless table until someone suddenly starts applying a constant force on it right until it reaches the end of the table. The book was constantly accelerating until it reached the end of the table. First, write down your thinking process as in the previous example, and then draw in the space provided below the book's motion diagram along with the velocity, acceleration, and force vectors. Draw book's motion diagram with velocity, acceleration, and force vectors. (Hint: Since the motion is horizontal, draw a horizontal motion diagram.)arrow_forwardC and D?arrow_forward

When the baseball leaves your hand, it has a speed of 6 m/s. (Assume there is no air resistance for this problem) a. Four seconds after you throw it, what is the acceleration of the baseball? Show your work and explain your steps. b. Four seconds after you throw it, what is the velocity of the baseball? Show your work and explain your steps.arrow_forward
