Question

a peg on a turntable moves with a constant tangential speed of \\(0.68\text{ m/s}\\) in a circle of radius \\(0.25\text{ m}\\). the peg casts a shadow on a wall. find the following quantities related to the motion of the shadow.

part a
find the period.
express your answer using two significant figures.
\\(t = \\) s

part b
find the amplitude.
express your answer using two significant figures.
\\(a = \\) m

Explanation:

Calculate the period of the motion

$$
LATEXBLOCK0
$$

Determine the amplitude of the shadow's motion

$$
LATEXBLOCK1
$$

Answer:

Question 1

\(T = 2.3\text{ s}\)

Question 2

\(A = 0.25\text{ m}\)
