Question

ALL NUMBERS ALREADY IN (WITH THE FUNNY MARKS AFTER) ARE CORRECT, IT IS ONLY THE ONES WITH BLANK SPACES

1) How much work was done on the real system?
W = joules

2) What is the change in energy of the real system?
?(Ktot + U) = joules

3) What is (Ktot + U)final for the real system?
(Ktot + U)final = joules

4) What is the final speed of the center of mass of the real system?
vcm,final = m/s

5) What is the final vibrational energy of the real system (spring potential energy plus kinetic energy relative to the center of mass)?
(U + Krel)final = joules

Explanation / Answer

it's your (Ktot+ U)final - Ktrans,final since Ktot = K trans + Krel

therefore your answer is 0.42 J
