Problem 28E

A cheerleader waves her pom-pom in SHM with an amplitude of 18.0 cm and a frequency of 0.850 Hz. Find (a) the maximum magnitude of the acceleration and of the velocity; (b) the acceleration and speed when the pom-pom’s coordinate is x = + 9.0 cm; (c) the time required to move from the equilibrium position directly to a point 12.0 cm away. (d) Which of the quantities asked for in parts (a), (b), and (c) can be found by using the energy approach used in Section 14.3, and which cannot? Explain.

Step-by-Step Solution:

Solution to 28E Step 1 Introduction A cheerleader is waving her pom-pom in SHM. We need to find the parameters of SHM. The following formulas are used. Given, Amplitude=18cm=0.18m Frequency=0.85Hz
