A block of mass 1.77 kg sliding with a constant velocity of 4.89 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 4.30 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 1.77-kg and 4.30-kg blocks, respectively, after their SECOND collision with one another?     0.45 m/s and 2.98 m/s     1.12 m/s and 8.41 m/s     4.02 m/s and 1.17 m/s     2.88 m/s and 4.79 m/s

The A hockey puck moving at 0.49 m/s collides elastically with another puck that was at rest. The pucks have equal mass. The first puck is deflected 37° to the right and moves off at 0.36 m/s. Find the speed and direction of the second puck after the collision. magnitude direction m/s to the left

Same situation as before. This time it s a block of mass 1.07 kg sliding with a constant velocity of 3.51 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 4.28 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 1.07-kg and 4.28-kg blocks, respectively, after their SECOND collision with one another?

Same situation as before. This time it s a block of mass 1.45 kg sliding with a constant velocity of 4.84 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 4.08 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 4.08-kg blocks, respectively, after their SECOND collision with one another?     0.92 m/s and 2.65 m/s     2.30 m/s and 7.88 m/s     3.44 m/s and 0.90 m/s     3.12 m/s and 4.39 m/s

A(n) 13 g object moving to the right at 27 cm/s overtakes and collides elastically with a 26 g object moving in the same direction at 13 cm/s. Find the velocity of the slower object after the collision.Answer in units of cm/s. Find the velocity of faster object after the collision.Answer in units of cm/s.

A 50 kg50 kg soccer player jumps vertically upwards and heads the 0.45 kg ball as it is descending vertically with a speed of 30 m/s. (a) If the player was moving upward with a speed of 4.0 m/s just before impact, what will be the speed of the ball immediately after the collision if the ball rebounds vertically upwards and the collision is elastic? (b) If the ball is in contact with the player's head for 21 m/s, what is the average acceleration of the ball? (Note that the force of gravity may be ignored during the brief collision time.)

A steel ball of mass 0.5 kg is fastened to a cord that is 70.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal. At the bottom of its path, the ball strikes a 2.5 kg steel block initially at rest on a frictionless surface. The collision is elastic. Find (a) the speed of the ball and (b) the speed of the block both just after the collision.
