Block 1, of mass m1, moves across a frictionless surface with speed
ui . It collides elastically with block 2, of mass m2, which is at
rest (vi = 0). After the collision, block 1 moves with speed uf ,
while block 2 moves with speed vf . Assume that m1 > m2, so that
after the collision, the two objects move off in the direction of
the first object before the collision.
What is the final speed uf of...

Two blocks are moving along the r-axis. Block A is moving with a velocity of +25 cm and Block B is moving with a velocity of-15m. The mass of Block A is 250g and the mass of Block B is 150g. If the two blocks stick together what is their final velocity? If the two blocks collide elastically what are their final velocities?

Two blocks are free to slide along the frictionless wooden track shown below. The block of mass m1 = 5.03 kg is released from the position shown, at height h = 5.00 m above the flat part of the track. Protruding from its front end is the north pole of a strong magnet, which repels the north pole of an identical magnet embedded in the back end of the block of mass m2 = 9.50 kg, initially at rest. The...
