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?

an object with a mass of (m) is moving along the x-axis according the the equation x(t) = at^2 -2bt, where a and b are positive constants.
what’s the magnitude of the net force at a time of t=0? express the answer in terms of m and a.
We start with some review problems A crate of mass 46.1 kg rests on a level surface, with a coefficient of kinetic friction 0.234. You push on the crate with an applied force of 389 N. What is the magnitude of the crate s acceleration as it slides?
6.14 m/s^2
8.44 m/s^2
2.46 m/s^2
13.50 m/s^2
The car manufacturer wants to see how the mass of the car affects the force required to accelerate the car by the same amount. A second set of trials are run in order to see how much force is needed to accelerate cars of different masses.

- If a single constant force acts on an object that moves on a straight line, the objects velocity is a linear function of time. The equation v = vi + at gives its velocity v as a function of time, where a is its constant acceleration. What if velocity is instead a linear function of position? Assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = vi kx, where k is a constant coefficient and x is the position of the object.
