Chapter 4, Problem 63EAP
You’ve been assigned the task of using a shaft encoder—a device that measures the angle of a shaft or axle and provides a signal to a computer—to analyze the rotation of an engine cranks haft under certain conditions. The table lists the crankshaft’s angles over a 0.6 s interval.
Time (s) Angle (rad)
0.0 0.0
0.1 2.0
0.2 3.2
0.3 4.3
0.4 5.3
0.5 6.1
0.6 7.0

A Ferris wheel has a radius of 42.4 feet. The bottom of the Ferris wheel sits 0.8 feet above
the ground. You board the Ferris wheel at the 6 o'clock position and rotate counter-
clockwise.
a. Define a function, f that gives your height above the ground (in feet) in terms of the
angle of rotation (measured in radians) you have swept out from the 6 o'clock
position, a
f(a)-42.4sin(a)+43.2
Preview
b. Define a function, g, that gives your height above the ground (in feet) in terms of the
number of feet you have rotated counter-clockwise from the 6 o'clock position, s.
g(s)=43.2+42.2sin(s/42.4)

In my assignment, I was asked to perform a lab experiment. I was to take a provided ball and roll it at a given angle at measured increments - 0.1m-.8m. I measured the time in seconds it took to go from 0 to each point - 0-.1, 0-.2, etc. My lab assignment asked me to perform each step three times. I did this, rolling the ball 3 times from 0-0.1 and calculating the time. I used an app on my phone, slowed down, and went to the closest time interval I could for each test. Naturally, my results for each of the 3 tests for all 8 distances was a bit off, as I would expect given my inexperience and inaccuracy of the tools used to begin with. The lab then asks to chart these values - which I inserted a chart of each trial, the time of each trial, and then calculated the average time ((trial 1 + trial 2 + trial 3)/3). The part I am stuck on is that the next activity it asks me for is: "Calculate the square of the average time for each distance, then create a graph of displacement vs. time…
Case 1: A DJ starts up her phonograph player. The turntable accelerates uniformly from rest, and takes t1 = 10.7 seconds to get up to its full speed of f1 = 78 revolutions per minute.Case 2: The DJ then changes the speed of the turntable from f1 = 78 to f2 = 120 revolutions per minute. She notices that the turntable rotates exactly n2= 16 times while accelerating uniformly.
a)How many revolutions does the turntable make while accelerating in Case 1?
b)Calculate the magnitude of the angular acceleration of the turntable in Case 1, in radians/second2.
c)How long (in seconds) does it take for the turntable to go from f1 = 78 to f2 = 120 RPM?

These problems will be pure math problems, meaning that we won't use units. a(t) = dv/dt = 38 cos(3t) v(t) = dx/dt, v(0) = -4, and x(0) = 8 Calculate v(8).
