Answer:
a) 72mJ
b) 0.33m/s
c) 54mJ
d) 18mJ
Explanation:
(a) The total energy of the system is given by:
where k is the force constant and A is the amplitude. By replacing we get:
= 72mJ
(b) we can get the speed by the conservation of energy (the kinetic energy and potential energy must equal the total energy in any place):
where we have used that x=1.15cm=0.0115m; A=6.00cm=0.06m
(c) Again, by the conservation of energy:
(d)
