The envelope and basket of a hot-air balloon have a combined weight of 2.45kN, and the envelope
Question:
The envelope and basket of a hot-air balloon have a combined weight of 2.45kN, and the envelope has a capacity (volume) of 2.18 x 103 m3. When it is fully inflated, what should be the temperature of the enclosed air to give the balloon a lifting capacity (force) of 2.67kN (in addition to the balloon's weight)? Assume that the surrounding air, at 20.0oC, has a weight per unit volume of 11.9 N/m3 and a molecular mass of 0.028 kg/mol, and is at a pressure of 1.0 atm.

As we know, to break a coconut we have to apply 400 pounds of pressure to it. In pounds = 400psi In newton = 1779.29N Starting from the first person he will try to break the coconut with his hands. As we know humans can exert a force 292 newtons by their hands. So force by hand is approximately = 300 N Then the second and third one also try to break it by hand but they fail too.
