An irregularly shaped stone was lowered into a graduated cylinder holding a volume of water equal to 2 ml. the height of the water rose to 7 ml. if the mass of the stone was 25 g, what was its density? t

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m.the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.

If an athlete runs once around a track, back to the starting line, her average velocity is zero. true or false?
