Groups of skydivers need to navigate through the air during a jump to get into a formation. How can skydivers who are below the formation join the group?

They can spread their bodies to slow their acceleration.
They can spread their bodies to decrease the strength of gravity.
They can form their bodies into a ball to slow their acceleration.
They can form their bodies into a ball to decrease the strength of gravity.

They can spread their bodies to increase their surface area and create more drag, slowing their descent and allowing them to catch up to the formation above. Additionally, they can use their arms and legs to steer themselves towards the group and adjust their body position to match the speed and direction of the formation. Communication through hand signals and verbal cues can also help coordinate the movements of the skydivers and ensure they join the group successfully.
