Answer:
In That Case, It Gets Rid Of The Heat By Evaporating Water (sweat). During Bicycling, A Typical 72.0 Kgperson's Body Produces Energy At A Rate Of About 501 W Due To Metabolism ... If the air temperature is the same as the temperature of your skin (about 30 ∘C), your body cannot get rid of heat by transferring it to the air.

Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. Stars are typically classified by their spectrum in what is known as the Morgan-Keenan or MK system.
        
             
        
        
        
Answer:
v = 15.8 m/s
Explanation:
Let's analyze the situation a little, we have a compressed spring so it has an elastic energy that will become part kinetic energy and a potential part for the man to get out of the barrel, in addition there is a friction force that they perform work against the movement.  So the variation of mechanical energy is equal to the work of the fictional force
      = ΔEm =
 = ΔEm =  -Em₀
 -Em₀
Let's write the mechanical energy at each point
Initial
     Em₀ = Ke = ½ k x²
Final
     = K + U = ½ m v² + mg y
 = K + U = ½ m v² + mg y
Let's use Hooke's law to find compression
     F = - k x
     x = -F / k
     x = 4400/1100
     x = - 4 m
Let's write the energy equation
     fr d = ½ m v² + mgy - ½ k x²
Let's clear the speed
    v² = (fr d + ½ kx² - mg y) 2 / m
    v² = (40 4.00 + ½ 1100 4² - 60.0 9.8 2.50)   2/60.0
    v² = (160 + 8800 - 1470) / 30
    v = √ (229.66)
    v = 15.8 m/s
