It is past midnight and Sue is sliding down a rope from her third floor window to meet her boyfriend. As she slides down the rope faster and faster she becomes alarmed and gradually tightens her grip on the rope. Thus the tension in the rope gradually increases. When the tension becomes equal to Sue's weight (ignore the mass of the rope), A. (a) Sue will stop. B. (b) Sue will slow down. C. (c) Sue will continue downward at constant speed. D. (d) the rope will break.

Two objects accelerate at 1 m/s2.  How do the applied forces compare? A. They are different B. They are the same C. I can't tell without the mass For a given object, which force due to friction is typically larger? A. They are different B. Kinetic friction  C. Static friction D. Now way to tell without knowing the mass

a. An object that is free-falling is acted upon by the force of gravity alone. b. A falling skydiver which has reached terminal velocity is considered to be in a state offree fall. c. A ball is thrown upwards and is rising towards its peak. As it rises upwards, it is NOT considered to be in a state offree fall d. An object in free fall experiences an acceleration which is independent of the mass of the object. e. A ball is thrown upwards, rises to its peak and eventually falls back to the original height. As the ball rises, its acceleration is upwards; as it falls, its acceleration is downwards. f. A ball is thrown upwards, rises to its peak and eventually falls back to the original height. The speed at which it is launched equals the speed at which it lands. (Assume negligible air resistance.) g. A very massive object will free fall at the same rate of acceleration as a less massive object.

A person pushes a box with a small constant force to move the box along the floor at a constant speed in a straight-line path.  Which of the following statements is true?   a. The net force on the box is zero.   b. There are no other forces on the box  (besides the person’s push.)   c. The net force on the box must be greater than zero to keep the box moving.   d. The box has an acceleration that is not zero.   e. [Both (c) and (d) are true.]

2.  A chain consists of identical links, each with a mass of 2.5 kg. You grab the top link and hold the chain at rest so that it hangs vertically.    a)  Draw a free body diagram of the bottom three links (labeled 1, 2, 3). Label all forces and use double subscript notation to denote which object exerts the force and which object is experiencing the force.   b)  Find the magnitude of the force exerted on link 1 by link 2, in Newtons.   c)  Find the magnitude of the force exerted on link 2 by link 3, in Newtons.

How would we describe the following scenario   A child rides their sled at a constant speed down an hill. There is friction between the ground and the sled.   a.   Force Constant   b.   Centripetal Acceleration   c.   Hooke's Law   d.   Translational Equilibrium   e.   Static Friction

A worker pulls a crate of mass, m, via a uniform, massless cable that is attached to the crate at an angle, θ, above the horizontal. The resultant tension in the cable is T. What is the normal force acting on the crate? a. mg b. mg + Tsinθ c. mg - Tcosθ d. mg - Tsinθ e. Tsinθ
