Dos ciclistas, A y B, viajan a velocidad constante sobre una carretera rectilinea en una misma direccion. Si se sabe
que A viaja a 10 km. h y B lo hace a 15 km/h y ademas
que A parte 3 horas antes que B, ¿a que distancia alcanza B a A?

A36,287 kg truck has a momentum of 907,175 kg • . what is the truck’s velocity

What would occur if the index of refraction of a material was less than n=1? the speed of light would increase to a speed larger than the maximum speed of light in a vacuum. the light wave would not bend at all though the material. the light wave would not be able to refract and would instead reflect off of the material. the speed of light would reduce to values close to 0 m/s.
