Answer:
hello your question is incomplete hence I will give you a general answer on how a stunt cyclist performs his stunts successfully
answer ;
The stunt cyclist trying to perform some sort of stunt with the bicycle will be faced with some forces like the static fiction between the tires of the bicycle and wall and also a centripetal force.
In order to overcome the centripetal force the minimal grip of the bicycle must be equal to the weight and the speed at which the cyclist must go can be represented as :

In order to overcome the centripetal force the minimal grip of the bicycle must be equal to the weight and the speed at which the cyclist must go can be represented as :
where ; r = radius of the tunnel where the stunt is to be performed
g = gravitational speed
u = coefficient of static friction
Answer:
Cost= 0.5 $
Explanation:
Coefficient of performance of the air conditioning system is given as
Energy = energy discharged or vented every hour= m c ΔT
Q = heat energy (Joules, J)
m = mass of a substance (kg)
c = specific heat (units J/kg∙K)
∆ is a symbol meaning "the change in"
∆T = change in temperature (Kelvins, K)
therefore
where m = ρV = density of air x volume = 1.20 x 200 x 2.4 = 576Kg
Energy = energy discharged or vented every hour= ρVc ΔT
Q= 576 x 1.005 x 10 = 5760 KJ/hour
therefore=ore 1kw = 3600KJ/hour
Q = 1.6 Kwh
Q =
Cost = per unit cost x energy vent x no of hours
Cost = 0.1 x 0.5 x 10
Cost= 0.5 $
