Compute the impact speed of a body released from rest at an altitude h = 426 mi. (a) assume a constant gravitational acceleration g0 = 32.2 ft/sec2 and (b) account for the variation of g with altitude. neglect the effects of atmospheric drag.

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.
