Textbook Question
Chapter 5, Problem 4EP
Suppose that the initial height of the object were measured from the top of the object at the release point to the floor. How would this affect your experimental result for g, that is, would it be too high or too low? Is this a random or a systematic error? (See Experiment 2 on errors.)

Assuming the initial velocity iszero and the acceleration is constantobtain the equation that allows thefinal instantaneous velocity v to becalculated from the distance d and thetime.
*please answer using variables so I can plug in the actual experimental values
An experiment is performed in an ideal condition to find out the velocity of a particle obeying the equation S=vtS=vt where the distance travelled (S)(S) inside a labeled glass tube by a particle with an uniform velocity (v)(v) is measured with respect to time taken (t)(t). The data collected by repeating the experiment five times is shown in the table below
If we use the method to minimize the squared sum error, what is the most likely velocity of the particle among the given options?

Assuming no uncertainties, using the slope of the line on the A vs F graph, determine the mass.

As you may also know, the drag force acting on a car is determined experiementally by placing the car in a wind tunnel. For a given car, the experimental data is generally represented by a single coefficient that is called the drag coefficient.
