A 1.9 kg object that stretches a spring 6.9 cm from its natural length when hanging at rest oscillates with an amplitude of 8.4 cm. The acceleration of gravity is 9.81 m/s2. Find the following
A) Find the total energy of the system.
B)Find the gravitational potential energy at maximum downward displacement.
C) Find the potential energy in the spring at maximum downward displacement
D)What is the maximum kinetic energy of the object?
