1. Draw a free-body diagram of a woman pushing a chair across the room with constant velocity to the right 2. Draw a free body diagram of a man successfully pulling a dog into shop. Dog sitting still and not pulling in the other direction

3. Draw a free-body diagram of an applied force pushing a block across a table at steady speed. Since you’re exerting a force on it, why isn’t it accelerating? Identify all the forces and draw a free body diagram. How does the pushing force compare to the friction force? Is it greater than, less than, or equal to the friction?

4. Draw a free body diagram of you pushing the same block quickly, then release it so it slides some distance before stopping. Determine the direction of acceleration based on Newton’s Second Law.

5. Now let’s add numbers to #4 The box is 7.5kg in mass and is moving at 2.3m/s before you release your push. It stops in 2second. Find the coefficient of friction.

6. A 1000kg block hangs on a rope
Find the tension on the rope if the block is:
 a) hanging on the rope

 b) moving upward at a steady speed of 5m/s

 c) accelerating upward at 5m/s2

7. A 5.5kg bucket is raised out of a well that is 20m deep, what is its acceleration if it takes 10 seconds to reach the top of the well. Ignore air resistance. What is the tension force on the rope to do this task?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
