Calcula la distancia que debe haber entre un pisa papel y una biblia tipo masas son de 250g y 650g con una fuerza cuya magnitud es de 1.85 x 10-6 dinas.

  r = 0.765 m

Explanation:

For this exercise let's use the law of universal gravitation

        F =

        r =

let's reduce the magnitudes to the SI system

         m₁ = 250 g (1 kg / 1000g) = 0.250 kg

         m₂ = 650 g (1 kg / 1000g) = 0.650

         F = 1.85 10-6 dynes (1 N / 10⁵ dynes) = 1.85 10-11 N

let's calculate

        r =

        r = √0.58587

        r = 0.765 m

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
