Same situation as before. This time it s a block of mass 1.45 kg sliding with a constant velocity of 4.17 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 4.22 kg, head-on, and rebounds back to the south, eventually colliding 100% elastically with a wall and rebounding northward. It then overtakes the second block, which is still moving north as a result of the first collision. What will be the speeds of the 1.45-kg and 4.22-kg blocks, respectively, after their SECOND collision with one another?     2.74 m/s and 3.85 m/s     1.24 m/s and 2.29 m/s     2.48 m/s and 6.96 m/s     2.86 m/s and 0.73 m/s

Block A (m=2.5kg) and Block B(m=3.5 kg, to the right of A) move on a frictionless horizontal surface. Initially, Blocl A is moving to the right st 6 m/s and Block B moves to the left with unknown speed. They collide head-on in a perfectly elastic collision. After the collision, block B moves to the right with a speed of 4.5 m/s. A) Find the speed of block B before the collision B)What is the velocity (magnitude and direction) of block A after collision?

A block of mass 1.15 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 3.78 m/s. It eventually collides with a second, stationary block, of mass 4.98 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.15-kg and 4.98-kg blocks, respectively, after this collision?      1.87 m/s and 1.89 m/s      1.89 m/s and 2.13 m/s      2.36 m/s and 1.42 m/s      1.42 m/s and 2.36 m/s

5) Same situation as before. This time it s a block of mass 1.55 kg sliding with a constant velocity of 5.62 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 3.17 kg, head-on, and rebounds back to the south, eventually colliding 100% elastically with a wall and rebounding northward. It then overtakes the second block, which is still moving north as a result of the first collision.
