Question

A 1.9 kg object that stretches a spring 8.8 cm from its natural length when hanging at rest oscillates with an amplitude of 6.5 cm. Find the total energy of the system. The acceleration due to gravity is 9.81 m/s^2
a) Find the total energy of the system.
Answer in units of J.
b) Find the gravitational potential energy at

maximum downward displacement.
Answer in units of J.
c) Find the potential energy in the spring at

maximum downward displacement.
Answer in units of J.
d) What is the maximum kinetic energy of the

object?
Answer in units of J.
NEED C & D:
PART A = .44744 PART B = -1.211535
