A puck move 2.35m/s in a -22.0 direction a hockey stick pushes it for 0.215s changing its velocity to 6.42 m/s in a 50.0 direction what was its velocity

hope it

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

the rearrangement of particles in a physical change. hope this
