Question

A particle of mass 2.00 kg is attached to a spring with a force constant of 300 N/m. It is oscillating on a horizontal frictionless surface with an amplitude of 4.00 m. A 7.00 kg object is dropped vertically on top of the 2.00 kg object as it passes through its equilibrium point. The two objects stick together.

(a) Does the amplitude of the vibrating system increase or decrease as a result of the collision?

decreases

increases

no change

(b)By how much does the amplitude of the vibrating system change as a result of collision?

m(b)

(c)How does the period change?

increases

decreases

no change

s(c)

(d)How does the mechanical energy of the system change?

no change

decreases

increases

By how much does the energy change?

J

(e) Account for the change in energy.
