Determine the coordinates of the center of mass for the system four masses, placed in the xy plane. m -1 kg at (3,0) m2 - 2 kg at (4,0) mg - 3 kg at (-1,-1) ma-4 kg at (-1,-2) O 4, 0) O 104, 0) O 14. -71 O 10.4, -1.1) В. Find the change in momentum of a 2 kg ball that traveled at 3 m/s before and after it bounced off a wall. +6Ns O-6NS O ONS O -12 Ns O 12 Ns A 1.5 kg ball has a velocity of 12 m/s just before it strikes the floor. Find the impulse on the ball if the ball bounces up with a velocity of 10 m/s. O 33 Ns O 18 Ns O 15 Ns O 3Ns C. A 2 kg baseball is thrown at 20 m/s. The batter hits the ball in the opposite direction at the same speed. The bat was in contact with the ball for 0.1 s. Find the magnitude of the force acting on the ball.
