1. You and your forensics team are working a crime scene of a 19 year-old female who was found in the woods behind the local hospital. She is found lying on her torso (face down), but lividity is present on the dorsal (back) side of the
victim.
What can you conclude about the victim/situation?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
