When a skydiver prepares to jump out of the plane. Then two forces will acts i.e. the force of gravity and frictional force. Both forces act in the opposite direction.
When the person starts accelerating towards the earth, the gravitational force is stronger.
When he opens the parachute, the surface area increases and hence the resistive force increase. As a result, he or she attains the terminal velocity.
Before the skydiver opens the parachute, his velocity would be increasing greatly as much as 9.8 m/s². Opening the parachute would increase the surface area to which air may cause resistance. The skydiver then reaches his terminal velocity.
Answer:Since the plane velocity and the wind velocity form a right triangle when added together in head-to-tail fashion, the angle between the resultant vector and the southward vector can be determined using the sine, cosine, or tangent functions. The tangent function can be used; this is shown below:
