A4.00-kg object is attached to a spring and placed on frictionless, horizontal surface. a horizontal force of 27.0 n is required to hold the object at rest when it is pulled 0.200 m from its equilibrium position (the origin of the x axis). the object is now released from rest from this stretched position, and it subsequently undergoes simple harmonic oscillations.
(a) find the force constant of the spring.
n/m
(b) find the frequency of the oscillations.
hz
(c) find the maximum speed of the object.
m/s
(d) where does this maximum speed occur?
x = ± m
(e) find the maximum acceleration of the object.
m/s2
(f) where does the maximum acceleration occur?
x = ± m
(g) find the total energy of the oscillating system.
j
(h) find the speed of the object when its position is equal to one-third of the maximum value.
m/s
(i) find the magnitude of the acceleration of the object when its position is equal to one-third of the maximum value.
m/s^2

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ftâ
lbflbmâ
r(1 psia144 lbf/ft2) = 0.3704 psiaâ
ft3lbmâ
r the amount of air that must be added to raise the pressure is lbm
