Two blocks of clay slide on a level, frictionless plane. block a, having a mass of 2.00 kg and traveling due south, collides with block b, having a mass of 3.00 kg and traveling 25.0 degrees west of due north. they stick together after the collision, and the resulting blob travels with a final speed of 9.89 m/s in a direction 39.9 degrees west of due north. calculate the initial speeds of blocks a and b.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
