A disk of radius 50 cm rotates about a center axle. The
angular position as a function of time for a point on the
edge of the disk is shown. Which two of the following
quantities of the point on the edge of the disk can be
correctly mathematically determined from the graph
using the methods described? Justify your selections.
Select two answers.
The angular velocity, because this
quantity can be determined by
calculating the slope of the graph.
A
The translational speed, because
В
V = rw.
The angular acceleration, because this
quantity can be determined by
calculating the area bound by the curve
and the horizontal axis from 0 s to 5 s.
The translation acceleration, because
a =
Angular Position (rad)
