IV1, Exam 3

Print out your results and bring them to your oral interview:

1. Use your data to construct graphs of the x and y position of the object as a
function of time.
2. From your graphs determine the amplitude, frequency, and phase angle of the x
and y motions.
Write the functions for these motions
x (t) =
y (t) =
3. From these functions determine the velocities and accelerations of the object in
the x and y directions.
4. From your results compute the angular velocity and radius of the path of the
object.
