A park ranger driving on a back country road suddenly sees a deer in his headlights 20 m ahead. The ranger, who is driving at 11.4 m/s, immediately applies the brakes and slows down with an acceleration of 3.80 m/s2. How much distance is required for the ranger's vehicle to come to rest? Only enter the number, not the units.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
