Aspace vehicle deploys its re–entry parachute when it's traveling at a vertical velocity of –150 meters/second (negative because the parachute is going down.) it comes to rest at 0 meters/second after 30 seconds. what's the average acceleration of the shuttle during this time span?

The slope of a velocity time graph over any interval of time gives the during that interval

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.
