A 1.5x103 kg car is constructed on a frame supported by four springs. Each spring has a spring constant of 2.5x104 N/m. If two people riding in the car have a combined mass of 1.6x102 kg, find the frequency of vibration of each spring when a car is driven over a pothole in the road and also find the period. Assume the weight is evenly distributed.

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 displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
