Hanging Spring When a 0.30 kg mass is suspended from a massless spring, the spring stretches a
distance of 2.0 cm.
Let 2.0 cm be the rest position for the mass-spring system.
The mass is then pulled down an additional distance of 1.5 cm and released.

Calculate the total mechanical energy of the system in SI units.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

the cellphone, they would then know if the killer would have contacted them or always hated them. or if it was a breakup. but if that is not the case, then it would be the clothing. to put in a bullet, it would have to be put in by hands. hands have finger prints which, would have giving you the answer of who done it.
