Justin, with a mass of 50 kg, is going down an 8.0-m-high water slide. he starts at rest, and his speed at the bottom is 12 m/s. part a how much thermal energy is created by friction during his descent? express your answer with the appropriate units.

The converted energy of is the thermal energy created by the friction during his descent.

Explanation:

Given information:

Mass of justin

Height of water slide

Speed at the bottom

Now, the total mechanical energy is:

And, the kinetic energy :

So, the energy lost by the justin:

Hence, this converted energy of is the thermal energy created by the friction during his descent.

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 answer is b ) square root of 5
