1. A penguin falls off a 35m cliff onto the head of a napping polar bear. The penguin starts from rest and accelerates due to gravity (9.8m/s2). How long does the penguin fall? (your final answer should be positive)
2. A penguin flees a cranky polar bear. The penguin starts from rest and runs at a constant acceleration east. At 20 seconds the penguin is running at a velocity of 2m/s. What is the acceleration of the penguin?

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.
