An 8.0 kg object moving to the right at 6.0 m/s suffers a head on collision with a 4 kg mass moving at 9.0 m/s to the left. After collision, the 8.0 kg object bounces back at 4.0 m/s. Draw or describe a diagram that explains the situation. In baseball , catcher A catches a pitched baseball with bare and stiff hands. Catcher B catches the baseball pitched at the same speed with a mitt and relaxed hands, so he can move it backward with the ball. Which of these two catchers is less likely to drop the catch ? Why ? Explain using equations.

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.
