A hanging spring stretches by 39.0 cm when an object of mass 490g is hung on it from rest. The object is then pulled down anadditional 15.5 cm and released from rest to oscillate withoutfriction.

a.) determine the position x at a moment 84.4 s later.

b.) determine the distance traveled by the vibrating object

c.) another hanging spring stretches by 39.5 cm when an object ofmass 480 g is hung on it from rest. The object is also pulled downan additional 15.5 cm and released from rest to oscillate withoutfriction. Determine its position x at a time 84.4 s later.

d.) determine the distance traveled by the vibrating object.

a).An object of mass 541 g is attached to a spring with springconstant k = 653 N/m. If the object is displaced by 130 mm from theequilibrium position and is released, with what speed doe theobject pass through the equilibrium position during itsmotion?

Express the result in the unit [m/s] and to three significantfigures. If you must use scientific notation, please enter asfollows: e.g. 0.000123 = 1.23E-4. Only answer in numerical values,no units. For negative numbers, leave no space between the negativesign and the number: e.g. right: -1.00, wrong: - 1.00.

b).An object has a mass of m = 647 g. It is attached to a springwhich has a spring constant of value k = 65 N/m. At time t = 0 theobject is pulled to a distance of 28.1 cm from its equilibriumposition (which you may choose conveniently at x = 0). The surfaceon which the object moves is frictionless.

What is the total energy of the system?

Express the result in the unit [J] and to three significantfigures. If you must use scientific notation, please enter asfollows: e.g. 0.000123 = 1.23E-4. Only answer in numerical values,no units.
