A particle starts at velocity of 3 m/s and accelerates uniformly at 1.5m/s². How far does it go in 1s, 5s and the 4th second

Please go through the 2nd photo for the last part of the question that is " how far does it go in the 4th second "

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.
