The velocity of a simple harmonic oscillator is given by:
v = -9.55sin(21.8t) (mks units)
a.) What is its angular frequency?
b.) What is the amplitude of the motion in meters to two decimal places?
c.) To the nearest hundredth of a meter where is the mass at the time t=18.29 seconds?
d.) If the mass in letter c is 0.74 kg, what is the spring's potential energy to the nearest tenth of a joule?
e.) What is its kinetic energy to the nearest tenth of a joule?
