A triangular block `ABC` of mass `m` and side `2a` lies on a smooth horizontal plane is shown. There point masses of the `m` each strikes the block at `A, B` and `C` with speed as shown. After the collision the particle come to rest. Then

A cubical block of side a is moving with velocity v on a horizontal smooth plane as shown. It hits a ridge at point O. The angular speed of the block after it hits O is:

A uniform rod of mass M and length a lies on a smooth horizontal plane. A particle of mass m moving at a speed v perpendicular to the length of the rod strikes it at a distance a/4 from the centre and stops after the collision. Find a. the velocity of the cente of the rod and b. the angular velocity of the rod abut its centre just after the collision.
