A mass of 10 kg is positioned at the origin and connected by a light rod to a mass

of 5 kg with position vector (3i + 4j) m. At t = 0, the mass at the origin is given an

impulse of (20bi + 40bj) Ns and the second mass is given an impulse of (25bi + 30bj) Ns.

The kinetic friction coefficient between the masses and the floor is 0.6. Show that the net external force on the system has a magnitude of approximately 88 N and state the direction of this force.

Hence estimate the final location of the centre of mass relative to the floor.
