- Se aplica una fuerza de empuje de 450 N sobre bloque de 150kg de masa. Calcula la aceleración con la que moveremos el objeto.
C.- ¿Cuál es la masa de una bolsa de boxeo si al golpearlo con una fuerza de 50N
se aceleró a 5 m/s2
?

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

it has to be b, about 97 percent.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
