1. Complete the following table showing the relationship between mass and weight. Object Mass (kg) Weight (N) Melon 1 kg Apple 0.98 N Pat Eatladee 25 kg Fred 980 N 2. Different masses are hung on a spring scale calibrated in Newtons. a) The force exerted by gravity on 1 kg = 9.8 N. b) The force exerted by gravity on 5 kg = N. c) The force exerted by gravity on kg = 98 N. d) The force exerted by gravity on 70 kg = N. 3. Does a person diet to lose mass or to lose weight? Explain.

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.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
