Suppose the force of air resistance is proportional to the speed of the object and in the direction opposite the object's velocity. If you throw an object upward, when is the magnitude of the object's acceleration highest? A. It is highest at the top of its trajectory. B The acceleration of the object is the same throughout the entire trajectory. No answer text provided. It is highest right after the object is released.

16. Running without friction is impossible. In fact, to maximize your acceleration, you need to maximize the static friction between your shoes and the floor. a) Explain why static friction is necessary for running or walking. requirement, employees' shoes must have a coefficient of static friction of 0.5 or more on a specified tile surface. In an emergency, what is the minimum time interval in which a postal worker starting from rest can move a distance of 3 m on the tile surface? c) A typical athletic shoe has a coefficient of static friction of 0.8 when used on a running track. What is the minimum time interval in which an athlete starting from rest can move a distance of 100 m on a running track? b) To meet a U.S. Postal Service

9. A 100 kg man gets in an elevator on the 10th floor. He stands still on a scale, which is placed on the floor of the elevator, before the doors close, and the scale reads a value equal to his weight (the largest force of gravity on him). The doors close, and the elevator starts moving downward toward the 1st floor. The elevator speeds up until it reaches the 8th floor, at which point the elevator travels at a constant velocity, which it maintains until it reaches the 3rd floor, at which point it starts slowing down at a constant rate and stops by the time it reaches the 1st floor. Rank from greatest to least, the following quantities at following floors: 2nd, 5th, 9th. Explain your answers. (a) His mass (the question is asking for a ranking of the person's mass on the 2nd floor vs. the mass on the 5th floor vs. the mass on the 9th floor.) (b) His weight (c) Magnitude of normal force he exerts on the scale (d) Magnitude of normal force he exerts on the elevator floor.

An adventurous model got bored and decided to try something new. She went out to the top of a steep icy road and went down on a sled. If friction is so small that it can be neglected, which of the following statements correctly describes the physics in the situation? Ad B C Only gravity acts on the model-sled between points A and B. The model-sled experiences no acceleration between A and C. The sled will stop somewhere near B. There is no force acting on the model-sled between points B and C. The sled will continue moving with constant speed from B onwards.
