A 2.5-kg rock is dropped off a 32-m cliff and hits a spring, compressing it 57 cm. What is the spring constant? Round your answer to two significant figures. The spring constant, k, is
StartFraction N over m EndFraction.

4800 N/m

Explanation:

Given

mass of rock

Height of cliff

compression in the spring

Here, potential energy is converted into kinetic energy which in turn converts to elastic potential energy of the spring

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.
