A particle executes simple harmonic motion
with an amplitude of 4 . 5 cm.
At what positive displacement from the
midpoint of its motion does its speed equal
one half of its maximum speed? Answer in
units of cm.
002 (part 1 of 3) 10.0 points
A block of unknown mass is attached to a
spring of spring constant 8 . 9 N / m and under-
goes simple harmonic motion with an ampli-
tude of 10 . 4 cm. When the mass is halfway
between its equilibrium position and the end-
point, its speed is measured to be 33 . 2 cm / s.
Calculate the mass of the block. Answer in
units of kg.
