2. Two particles, P, of mass 2m, and Q, of mass m, ar e moving along th e sam e straight line on a smooth horizontal plane. They ar e moving in opposit e directions towards each other and collide. Immediately befor e th e collision th e speed of P is 2u and th e speed o...
At one instant, the center of mass of a system of two particles is located on the x-axis at x = 2.0 m. One of the particles is at the origin. The other particle has a mass of 0.10 kg and is at rest on the x-axis at x = 8.0 m. The mass of the particle at the origin is...
Two particles of massm1=1.9kgandm2=2.7kgundergo a one-dimensional head-on collision as shown in the figure below. Their initial velocities alongxarev1i=13msandv2i=-7.3ms.The two particles stick together after the collision(...
8.A BIm lm Figure 3Two particles A and B have mass 0.4kg and 0.3 kg respectively. The particles are attached to the ends of a light inextensible string. The string passes over a small smooth pulley which is fixed above a horizontal floor. Both particles are held, with the string tau...

We study a system of active particles with soft repulsive interactions that lead to an active cluster-crystal phase in two dimensions. We use two different modelizations of the active force - Active Brownian particles (ABP) and Ornstein-Uhlenbeck particl
