Explanation Introduction: If a book is pushed across a table it will exert a frictional force on the book which will stop. When the direction of motion of the book is positive, then the retardation due to frictional force is negative. So the book must have a positive velocity but a negative acceleration, in account with the direction. When the direction of motion of the book is considered negative, the velocity will also be negative. The frictional force causing retardation will be negative as it opposes the motion. So, the velocity and acceleration of book will be negative. The book must have a positive velocity, in account with the direction, but a negative acceleration. Thus, the position versus time graph will have a decreasing positive slope, whereas the velocity versus time graph will have a constant negative slope. The position versus time graph is shown below. Figure (1) The velocity versus time graph is shown below...

Students have asked these similar questions

Given: ruler 11.56 g, small washer 1.85 g each, large washer 24.30g each Use the data in Data Tables 4 and 5 to experimentally determine the mass of your ruler. Use one of your 2 trials with 1 small washer at 0 cm, one of your 2 trials with 2 small washers at 0 cm, and one of your 2 trials with 3 small washers at 0 cm to find three experimental values for the mass of the ruler. How do you experimentalls determine the mass?

Compare the 3 experimental masses of your ruler to the measured mass of your ruler (Data Table 1) by calculating the percent error for each experimental value. Which trial provided the best data for determining the mass of the ruler? Please help, I am not sure how to calculate this. Thanks!

Please help, everytime I try to input the data only one point shows on the graph. Please graph unsing centripetal force, Fc, versus V E2 from Activity 1. Include a line of best fit and record the equation of the line. Thank you!
