The graph below depicts the velocity of a marble rolling along a ramp, in cm / s, vs. clock time in seconds.
For the interval between t = 0 seconds and t = 6 seconds:
For the interval between t = 2 seconds and t = 5 seconds:
What is the total area between the horizontal axis and the straight line, between t = 0 and t = 6?
What is the total area between the horizontal axis and the straight line, between t = 2 and t = 5?
Results from Friday's experiment:
You should have run three trials for the strap rotating on the die. For each trial you were asked to estimate how many degrees in how much time for three trials, one in which the strap rotated less than 360 deg, on in which it rotates through several revolutions, and one in which the number of revolutions is somewhere between.
For each of your trials you were to determine the following
You will be asked for the following information, which you will give as five numbers in a row. Quickly organize your information so you can read it off when asked:
| trial number | time interval | total change in angular position | average angular velocity | angular acceleration |
