A particle of mass m= 0.1 kg moves with velocity v= 2 m/s along the negative direction of the y-axis. It impacts a disk of mass m = 0.4 kg and radius r = 0.2 m, which is stationary. After the collision, the particle moves with velocity V along the negative direction of the x-axis and the disk moves in the xy plane along a certain direction rotating with angular velocity w = 0.81 rad/s (Figure 4). The plane on which the motion occurs is frictionless. Evaluate (a) the velocity v1 of the particle after the collision (b) the velocity v2 of the disk after the collision (c) the direction of rotation of the disk (d) the change in kinetic energy due to the collision. Is the collision elastic or inelastic? V 45* A particle of mass m= 0.1 kg moves with velocity v= 2 m/s along the negative direction of the y-axis.
