Skydiving tunnels have become popular attractions, appealing in part to those who would like a taste of the skydiving experience but are too overwhelmed by the fear of jumping out of a plane at several thousand feet. Skydiving tunnels are vertical wind tunnels through which air is blown at high speeds, allowing visitors to experience bodyflight. On Natalya's first adventure inside the tunnel, she changes her orientation and for an instant, her 46.8-kg body momentarily experiences an upward force of air resistance of 521 N. Determine Natalya's acceleration during this moment in time.
