Calculate the final velocity of this system that experiences an inelastic collision. Two dinosaurs are charging toward each other and a collision is imminent.

A 5,800 kg triceratops moving at a velocity of 8 m/s

A 2,700 kg T-rex moving at a velocity of 20m/s. The two dinosaurs crash into each other (stick to each other) in an inelastic collision.

Set your coordinate system as positive in the direction that the triceratops is moving.

Treat this as a closed system and ignore all external forces.

Atomic nuclei of almost all elements consist of

Estimate the schwarzschild radius (in kilometers) for a mini-black hole formed when a superadvanced civilization decides to punish you (unfairly) by squeezing you until you become so small that you disappear inside your own event horizon. (assume that the your weight is 50 kg)
