Un objeto de masa m está en reposo en equilibrio en el origen. en t=0 se aplica una fuerza F(t) con componentes:

donde k1,k2 y k3 son constantes. Calcule losvectores de posición r(t) y velocidad v(t) en función del tiempo.

Which statement is true about an object that is moving in a circular motion due to centripetal force, f, when the radius of its circular motion is doubled? the new force then becomes equal to 2f the new force then becomes equal to f the new force then becomes equal to f/2 the new force then becomes equal to f2 the new force then becomes equal to 1/f
