Question:

A 1.15 kg mass oscillates according to the equatio
Please show all the work
A 1.15 kg mass oscillates according to the equation x=0.650 cos (8.40t) where x is in meters and t in seconds. Determine: the amplitude, the frequency, the total energy, and the kinetic and potential energy when x=0.360m

Answers

a) amplitude A = 0.65 m

b)

w = 8.4

frequency

f = w/1pi

f = 1.337 Hz

c)

Total energy

TE = 0.5 xm x(AW)2

TE = 17.14167 J

d)

PE = 0.5 xkx X2

PE = 0.5 m w^2 x0.36x0.36

PE = 5.5258 J

KE = TE-PE

KE = 11.8835 J
