Continue this same procedure by adding more mass, in the shape of the child, the adult, and the trash can. 2. To complete the table above, calculate the coefficient of static friction between the box and the ground. Keep in mind the equation for the equation, F₁ = μ*Normal. Be sure to show all your work and include any assumptions you make. Write out the final answer for the coefficient of friction as the average of the values in the table. 3. Using similar methods as in questions #1 and #2, estimate the mass of the object in the present, the mystery mass. Include a description of the process and the mathematics of estimating the mass. Use the average coefficient of friction written in # 2 to solve for the mystery mass. 4. Set an object (anyone you choose) to be moving at a constant speed. Describe the procedure for keeping the object moving at a constant speed. Write down the speed at which the object is moving, as well. 5. Using the equations of constant acceleration, estimate the time for the object to stop moving, once you remove all the applied force. Keep in mind you know the acceleration of the box because the force of friction is the only force, once the figure stops pushing on the box! Show all your calculations and work to receive full credit.
To setup the simulation, click all the options in the upper right corner, so you can see all the parameters for this simulation: Forces Sum of Forces Values Masses Speed None Then click on the single right arrow to increase the pushing force of the figure. Friction Click only a few times. You will notice that the box does not move! Continue to click until the box just barely begins moving. This will take some time, so be patient! 1. Lots Once you have just gotten the box to move, make a note of the force just previous to the one that caused the box to move. Add it into the table below.
