Block aon the left has mass 1.00 kg. block bon the right has mass 3.00 kg. the blocks are forced together, compressing the spring. then the system is released from rest on a level, frictionless surface. after the blocks are released, how does pa(the magnitude of momentum of block a) compare to pb(the magnitude of momentum of block b)?

Explanation:

Here, there are two blocks of mass 1 kg and 3 kg that are connected with a spring and nothing else is attached to the blocks.

One of the blocks is pulled and released. Since no other forces are acting the momentum is conserved so the magnitude of each block will be equal.

The velocities will be different as the mass of the block are different.

260 miles per hour

explanation:

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
