In experiment 2, we will be measuring the time it takes for a marble to roll different distances. We will plot the distance the marble moves LaTeX: d d as a function of LaTeX: t^2 t 2 . If the plot is a line (or a fair approximation), this means that we have constant acceleration. If the plot of LaTeX: d d as a function of LaTeX: t^2 t 2 has a slope of 2.73 m/s2, what is the acceleration? Please give your answer in units of m/s2 and 2 decimal precision.
Homework Answers
d = at^2 / 2
Where a is acceleration of marble.
In a plot of d as function of t^2, slope of line is a/2. Hence
Slope 2.73 m/s^2 = a/2
a = 5.46 m/s^2

100 cm H. A child rolls a marble on a bent track that is 100 cm long as shown in the figure. We use x to represent the position of the marble along the track. The child gives the marble some initial speed at x0 m and t 0 s and then watches it roll to x100 cm, where it turns around, eventually returning to x 0 m with the same speed with which the child released it. On the...

At your station will be a table of travel distance and the time a cart took to travel those distances. The cart is initially at rest. The overall goal will be to determine the cart’s acceleration. Plot the data (Or a function of the data, for example the square, or square root, or times something, or. . .) in such a way that: •The position is the independent variable, and plotted on the horizontal axis, •The acceleration is inversely proportional...

Below is an image from a double slit experiment obtained by shining a laser through one. I used a He-Ne Laser, wavelength = 632.8 nm, and shined through two slits whose separation distance is d = 0.250 mm. The light was shined upon a sheet of paper taped to the wall and was 10.0 ft 4.00 inches away from the double slit. I circled the bright spots (constructive interference) and identified the central maximum (m = 0). I saved the...

Using R-studio 2. Consider an experiment where we flip a fair coin six times in a row, and i is the number of heads tossed: a. Calculate the probability mass function for i = 0. . . 6 using the equation from Ross section 2.8 for Binomial Random Variables b. Conduct a simulation of this experiment in R, with T trials of the experiment – pick several values of T from 10 to 10,000. c. Create a plot of the...
