Acyclist going downhill is accelerating at 1.2 m/s2. if the final velocity of the cyclist is 16 m/s after 10 seconds, what is the cyclist's initial velocity? 4 m/s 12 m/s 18 m/s 20 m/s

Initial Velocity is 4 m/s

Explanation:

What is acceleration?

It is the change in velocity with respect to time, or the rate of change of velocity.

We can write this as:

Where

a is the acceleration

v is velocity

t is time

 is "change in"

For this problem , we are given

a = 1.2

t = 10

Putting into formula, we get:

So, the change in velocity is 12 m/s

The change in velocity can also be written as:

It is given Final Velocity = 16, so we put it into formula and find Initial Velocity. Shown Below:

hence,

Initial Velocity is 4 m/s

4m/s

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.
