Se tienen 2 vectores cuyos módulos están en la misma razón que 5 y 2. Si cuando forman 53º su resultante mide 3√29u, ¿Cuánto mide el mayor vector?

|v2| = 3.27

Explanation:

You have two vector v1 and v2. The relation between the magnitudes of both vectors is given by:

Furthermore, the projection (the dot product) of one vector on the other one is given by the following formula:

The dot product between v1 and v2 is 3√29. If you multiply the right hand side of the last equation by |v2|/|v2| you obtain:

you do |v2| the subject of the formula:
