Energy Conservation
A 5kg mass spring system is held in the current position of the
figure below. Given that the total energy of the system is 20J and
the spring constant is 2.50 N/m (ignore friction),
a) What is the current kinetic energy of the system?
b) What is the Amplitude(A) of the system?
The mass is then released. At the point x1, the mass
experiences a velocity of 1.80m/s.
c) What is the current total energy of the system at x1?
d) What is the elastic potential energy of the system at x1?
