Questions 1-2 refer to a toy car that can move in either direction along a horizontal line (the + position axis).<\/p>\n

Assume that friction is so small that it can be ignored. A force toward the right of constant magnitude is applied to the car.<\/p>\n

1. Sketch on the axes below using a solid line the shape of the car\u2019s acceleration\u2014time graph.<\/p>\n

2. Suppose that the mass of the car were twice as large. The same constant force is applied to the car. Sketch on the axes above using a dashed line the car\u2019s acceleration\u2014time graph. Explain any differences in this graph compared to the car\u2019s acceleration\u2014time graph with the original mass.<\/p>\n

3. When a force is applied to an object with mass equal to the standard kilogram, the acceleration of the mass is 3.25 m\/s2. (Assume that friction is so small that it can be ignored.) When the same magnitude force is applied to another object, the acceleration is 2.75 m\/s2. What is the mass of this object? What would the second object\u2019s acceleration be if a force twice as large were applied to it? Show your calculations.<\/p>\n

4. Given an object with mass equal to the standard kilogram, how would you determine if a force applied to it has magnitude equal to one newton? (Assume that frictional forces are so small that they can be ignored.)<\/p>\n

In Question 5, assume that friction is so small that it can be ignored.<\/p>\n

5. The spring scale in the diagram below reads 10.5 N. If the cart moves toward the right with an acceleration also toward the right of 3.25 m\/s2, what is the mass of the cart? Show your calculations and explain.<\/p>\n

In Questions 6 \u2013 8, friction may not be ignored.<\/p>\n

6. The force applied to the cart in Question 5 by spring scale F1 is still 10.5 N. The cart now moves toward the right with a constant velocity. What are the magnitude and direction of the frictional force? Show your calculations and explain your reasoning.<\/p>\n

7. The force applied to the cart in Question 5 by spring scale F1 is still 10.5 N. The cart now moves toward the right with an acceleration also toward the right of 1.75 m\/s2. What are the magnitude and direction of the frictional force? Show your calculations and explain.<\/p>\n

8. The force applied to the cart by spring scale F1 is 10.5 N. The cart now moves toward the right with a constant velocity. The frictional force has the same magnitude as in Question 7. What does spring scale F2 read? Show your calculations and explain.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
