My Notes Ask Your Teacher A mass is attached to the end of a spring and set into oscillation on a horizontal frictionless surface by releasing it from a stretched position. The position of the mass at any time is described by x (7.6 cm)cos 2nt/(4.68 s)]. Determine the following (a) period of the motion (b) frequency of the oscillations Hz (c) first time the mass is at the position x 0 (d) first time the mass is at the site of maximum compression of the spring Additional Materials Reading GMy Notes Ask Your Teacher - / 1 poirks osColPhys2016 16.4.WA.032. When a pendulurn with a perjod of 2.00000 s is moved to a new location from one where the acceleration due to gravity was 9.80 m/s, its new period becomes 1.99874 s By how much does the acceferation due to gravity differ at its new location? 625 PM 11/20/2019 Type here to search

Answer 1

a)

T = 4.68 s

b)

f = 1/T = 0.2137 Hz

c)

0 = cos ( 2 pi t / 4.68)

pi/2 = 2 pi t / 4.68

t = 1.17 s

d)

7.6 = 7.6 cos ( 2 pi t / 4.68)

pi = 2 pi t / 4.68

t = 2.34 s
