During the final stages of descent, asky diver with an
openparachute approaches the ground with a constant velocity.
Thewind does not blowhim from side to side. Is the sky diver
inequilibrium and, if so, what forces are seponsible for
theequilibrium?

Respuesta :

Answer:

Gravity: downwards

Air drag and air-pressure on the inner surface of the the parachute: Upwards

Explanation:

  • If a sky-diver is in the final stages of his descend with open parachute such that the wind is calm and it does not blows him laterally.
  • In such a condition the air resistance in the form of drag and the pressure force due to the air captured in the parachute are acting in the upward direction which balance the force of gravity on the body. But this situation may occur momentarily and then again the diver must begin to slowly descend.
