Chapter 5, Problem 41EAP
In lab, you propel a cart with four known forces while using an ultrasonic motion detector to measure the cart’s acceleration. Your data are as follows:
| Force (N) | Acceleration (m/s2) |
| 0.25 | 0.5 |
| 0.50 | 0.8 |
| 0.75 | 1.3 |
| 1.00 | 1.8 |
- How should you graph these data so as to determine the mass of the cart from the slope of the line? That is, what values should you graph on the horizontal axis and what on the vertical axis?
- Is there another data point that would be reasonable to add, even though you made no measurements? If so, what is it?
- What is your best determination of the cart’s mass?

I forgot my car in a no - parking zone. A tow truck pulled it away. The truck exerted a force of 4000 N on my car. There was friction between the car’s tires and the ground, and the force of friction was 600 N. My car was moving with an acceleration of 2 m/s2. What is the mass of my car? Write the solution to this question showing all the steps. Do not forget the units on your final answer.

- Just like Louis, Maria left a book on the roof of her car before driving away. The mass of the book was 725 grams. The coefficient of static friction between the book and the roof was 0.28. The coefficient of kinetic friction between the book and the roof was 0.23. Maria started her car and drove forward on level ground with an acceleration of 3.6 m/s?.

Rather, some other physical property is measured and the desired physical property is computed from the results. For example, a bathroom scale does not actually measure mass or "weight," but rather the compression distance of a spring. The numerical values on the scale are calibrated from the compression distance using basic physics principles such as Newton's second law. Coefficients of friction cannot be measured directly. In this problem, we are going to learn how we can indirectly measure the coefficient of kinetic friction between two surfaces by directly measuring the expansion of a spring. Consider a 5.45 kg5.45 kg block that is dragged by a spring on a (relatively) frictionless horizontal surface at constant velocity. Suppose the block reaches a rough patch and the spring stretches by 5.25 cm5.25 cm. Compute the coefficient of kinetic friction ?μ between the block and the rough patch if the spring…arrow_forward
