A45,000 kg train moves at a velocity of 12 m/s north. it collides with a 50,000 kg train moving 10 m/s south. if the collision is inelastic, what is the final motion of the trains?

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
