Abaseball is thrown directly upward at time t=0 and is caught again at time t=5s. assume that air resistance is so small that it can be ignored and that the zero point of gravitational potential energy is located at the position at which the ball leaves the thrower's hand. the points for part a are (0,100) (1,36) (2,4) (2.5,0) (3,4) (4, 36) (5,100). based on the graph of kinetic energy given (the points), sketch a graph of the baseball's gravitational potential energy. give specific points.

Animals respond in various ways to stimuli detected through their senses. some of these responses are stimulated by the presence of danger. which of these animal responses is the best example of a response to an immediate threat? a) a rooster crows every morning at the first sign of light. b) as something approaches an octopus, it shoots a cloud of ink. c) from late fall until spring, bears hibernate to preserve energy. reactivate d) a dog is getting hot in the sunlight, so he moves to a shaded area.
