Suppose that the metal cylinder were placed into a graduated cylinder filled with water, with markings of 1 ml, in order to find its volume by the amount of water it displaced, read to the nearest ±1 ml (note that i ml-1 cm) would this be less precise, more precise, or have approximately the same precision as calculating the volume from the given diameter and height measurements? 1 explain your reasoning.

Given :

One particle, of mass m , moves with a speed v in the x-direction, and another particle, of mass 2 m , moves with a speed v/2 in the y-direction.

To Find :

The velocity of the center of mass of these two particles.

Solution :

Speed of mass m, .

Speed of mass 2m , .

Speed of center of mass is given by :

Hence, this is the required solution.
