Stephen is riding an amusement park ride. His actual weight is N. At one point during the ride, Stephen is accelerating downward at a rate of m/s . What is Stephen's apparent weight during this period of acceleration? Correct Gravity acts downward, and the normal force acts upward. Calculate Stephen's mass, then use that value to find the normal force, which is equal to apparent weight. N N N N / 1 1 Points 3. Henry throws a -gram stone off of a cliff. What is the apparent weight of the stone while it is in free fall? Correct When an object is in free fall, the only force acting on it is gravity; there is no normal force. N N N N / 1 1 Points

Caroline is on an airplane. At one point in the flight, she measures that her luggage has an apparent weight of N. The actual weight of her luggage is N. Which of the following best describes the vertical motion of the airplane? Correct Gravity acts downward, and the normal force acts upward. Calculate the net force, as well as the mass of the luggage, to find the acceleration. The airplane is accelerating upwards at m/s The airplane is accelerating upwards at m/s The airplane is accelerating downwards at m/s The airplane is accelerating downwards at m/s / 1 1 Points 5. Which of the following is an example of a normal force? Correct The normal force is an upward force, perpendicular to the ground, that counteracts the downward forces, such as gravity. the friction between a book and the ground it rests on the force of gravity that pulls a book downward the gravitational force that a book exerts on the Earth the force of the ground pushing upward on a book / 1 1 Points
