1.1.A 2.00 kg particle has the xy coordinates ( -1.20 m, 0.500 m), and a 4.00 kg particle has t coordinates (0.600 m, -0.750 m). Both lie on a horizontal plane. At what (a) X and (b) y coordina' you place a 3.00 kg particle such that the center of mass of the three-particle system has the coo: 0.500 m, - 0.700 m)? 1.2.Figure 9-35 showsa three-particle system, with massesmkg, IQ = 4.0 kg, andmg = 8.0 kg.

A 10.0-g bullet is red into a stationary block of wood having mass m = 5.00 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0. What was the original speed of the bullet? 2.2.A 12.0-g wad of sticky clay is hurled horizontally at a 100-g wooden block initially at rest on a in surface (Fig. 2.2). The clay sticks to the block. After impact, the block slides 7.50 m before con rest. If the coefcient of friction between the block and the surface is 0.650, What was the speed of the ler immodiatplv hpfnrp imnnpt
