Likely an instant death. If it hit her unawares, she was alive one second, and gone to this world in the next second, never knowing anything unusual was happening. Like a safe falling on someone from three stories up that a work crew was delivering to a balcony.
Something similar happened in Little Rock Arkansas in 1969 when I was there in the USAF. A dual rear wheel and brake drum assembly came off the rear axle of a dump truck on I-40 in downtown Little Rock, crossed the median at 65 MPH, and hit an oncoming Volkswagen beetle head on. The two people in the bug were killed instantly.
When I was driving the big rig, I drove most of my miles on I-10 between Mobile and San Antonio. I often stopped at the east bound rest area in Mississippi. One day, I noticed bright orange paint on the asphalt, the outline of a body, in the parking spot there. I saw more spots of sprayed paint on the grass, it led on a trail back to the interstate, 400 feet away. I talked to a cop there, he said an 18 wheeler going west bound had lost a wheel, travelled 400 feet at 70 mph, hit a college girl in the head.

Those wheels rolled through the eastbound lanes and into the rest stop striking the student from Tulane University in New Orleans.
Police say she and her two friends had stopped to use the restroom and were about get back into their car when the truck tires struck one woman and smashed into their car and an SUV parked next to it.
