Denote the initial speed of a cannon ball fired from a battleship as v0.the time of flight tmax of the cannonball for this maximum range r is given by when the initial projectile angle is 45◦ with respect to the horizontal, it gives a maximum range r.

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.
