Missy Diwater the former platform diver for the Ringling Brother's circus had a kinetic energy of 15000 j just to prior to hitti
1 answer:
Missy's velocity is 24.5 m/s
Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion. Mathematically, it is given by
where
m is the mass of the object
v is its velocity
In this problem, we know:
K = 15000 J is Missy's kinetic energy
m = 50 kg is her mass
Solving for v, we find her velocity:

<h3>What is infrared radiation?</h3>
An infrared telescope is tuned to detect infrared radiation with a frequency of 9.45 THz.
We know that,
1 THz = 10¹² Hz
So,
f = 9.45 × 10¹² Hz
We need to find the wavelength of the infrared radiation.
λ=c/f
λ = 3×/9.45×
λ = 3.174 × m
The term "infrared radiation" (IR) refers to a part of the electromagnetic radiation spectrum with wavelengths between about 700 nanometers (nm) and one millimeter (mm). Longer than visible light waves but shorter than radio waves are infrared waves.
Electromagnetic radiation with wavelengths longer than those of visible light is known as infrared, also known as infrared light. Since it is undetectable to the human eye, The typical range of wavelengths considered to be infrared (IR) is from about 1 millimeter to the nominal red edge of the visible spectrum, or about 700 nanometers.
