Question

Can you please work each part of the question and show complete work? Trying to understand each concept for exam.

grammatically correct English sentences. You may supplement these sentences with equations, but keep these to a minimum and EXPLAIN what the symbols mean! I want most of the answer to be in WORDS! (Note: Answers with ONLYsymbols, with no explanation. about what they mean, will receive NO credit!) a. (2 points) See figure. A box of mass m is sliding at constant velocity v across a flat, horizontal, frictionless surface. Sketch the free body diagram for the box. Is there a force in the direction of the motion (parallel to the velocity? WHYor WHYNOT? Explain (in English!) your answer using Newton's Laws! b. (2 points) See figure. A child sits in a wagon, which is moving to the right (x-direction) at constant velocity vox. She throws an apple straight up (from her viewpoint) with an initial velocity voy while she continues to travel forward at Vox. Neglect air resistance. Will the apple land behind the wagon, in front of the wagon, or in the wagon? WHY? Explain (briefly!) your answer. se what you know about projectiles!). Make a sketch of the situation to illustrate your explanation c. (2 points) A box of mass m sits statically (not moving) on a flat horizontal table. The figure is the box's free body diagram when the only forces acting on it are the normal force FN upward & it's weight mg downward. Is the normal force FN in this case equal in size & opposite in direction to the box's weight mg? Which Newton's Law of Motion did you use to answer this? d. Briefly in a sentence or two Define Static Equilibrium e. Briefly state THE THEME OF THE COURSE. (Note: I've stated this several times in class, beginning at our first meeting! It's also on the webpage & in some downloadable lectures!)

Answer 1

I think part d and e you should answer yourself. If you aren't clear on anything, please message me back
