Thank you mam🙏🙏
A ball of mass 1kg moving along X-direction collides elastically with a statioinery ballof mass m.The first ball(mass=1kg) recoils at right angles to its original direction of motion.if the second ball starts moving at an angle 30 degrees with the x axis, Find the value of "m"

  2. ELASTIC COLLISION IN TWO DIMENSIONS In general, the collision are two dimensional, where the initial velocities and the final velocities may lie in a plane. So, when two bodies travelling initially along the same straight line collide without loss of kinetic energy and move along different directions in a plane after collision, the collision is said to be elastic collision in two dimensions

  5. PROBLEMS OF COLLISIONS: Cart A (50. kg) approaches cart B (100. kg initially at rest) with an initial velocity of 30. m/s. After the collision, cart A locks together with cart B. both travels with what velocity? . Before collision after collision mA 50 kg, vA 30. m/s ( + ( ( = v 10. m/s mass increases by 3 times (50 kg to 150 kg), speed decrease by 3 times (30 m/s to 1O m/s)

  6. A block of mass M initially at rest on a frictionless horizontal surface is struck by a bullet of mass m moving with horizontal velocity v. What is the velocity of the bullet-block system after the bullet embeds itself in the block? Before collision mv M(O) mv O after collision (m M)v mM)v' mv / (M+m)v'
