avutons cqual! *71. In a collision, an automobile initially traveling at 60 km/h decelerates at a constant rate of 200 m/s. A passenger not wearing a seat belt crashes against the dashboard. Before the collision, the distance between the passenger and the dash- board was 0.60 m. With what speed, relative to the automo- bile, does the passenger crash into the dashboard? Assume that the passenger has no deceleration before contact with the dashboard.
