A runner increases his velocity from 0 m/s to 20 m/s in 2.0 s. what is his average acceleration?

10 m/s²

his average acceleration is a (m/s²).

we have:

a = (20 - 0)/2.0 = 10 (m/s²)

Explanation:

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.
