Three masses move on a flat, frictionless surface as shown in the diagram below. Mass2 is moving horizontally towards the right, and Mass3 is moving vertically upwards. Mass1 is moving towards the other two at angle (shown on diagram). The values of masses, initial velocities and angle are also shown below. They collide in a perfectly inelastic collision, so that they are stuck to each other after the impact, forming a single, larger mass. Determine: a) The velocity (magnitude and direction) of the resulting mass after collision. b) The kinetic energy lost (to heat and sound) during the collision. m1 m¡ = 6.8 kg Vị = 10.3 m/s m2 8, = 45° v2 m2 = 7.3 kg V2 = 15.7 m/s m3 = 4.2 kg %3D v3 V3 = 6.5 m/s m3
