2.7 Paper clips, or if rounded, 3 whole paper clips.
The magnitude of the object's velocity is
√ (5.1² + 2.82²) = √ (33.9624) = 5.828 m/s .
Kinetic energy = (1/2) (M) (speed²)
= (1/2) (5.22 kg) (5.828 m/s)²
= (2.61 kg) (33.9624 m²/s²)
= 88.64 kg-m²/s²
= 88.64 Joules

The phenomenon that is observed when an incident ray travelling in a slower medium strikes the boundary of a faster medium with an angle greater than the critical angle is known as total internal reflection.
Total internal reflection results in the the ray being reflected within the medium, instead of leaving it after undergoing diffraction. This phenomenon is the working principle of optical fibers.
I may be wrong but does it mean it was revent? because i know shortly after someone dies your body becomes fully stiff so maybe it was recent and it's in the process off stiffening up
