- Four forces act on a 10-kg mass in the force diagram below: a) Label the force diagram to the right with the correct symbol for each force arrow or vector. b) What is the acceleration of this 10-kg mass above? Show equation, plug in number with units, circle answer with correct units.arrow_forwardYour little brother is playing with monkeys in a barrel. The mass of each monkey is indicated in the illustration on the right. Note that your brother is holding the monkeys still and his hand weighs 50 N. Use Newton’s 1st and 3rd laws to numerically determine all of the forces acting on the monkeys and the hand. If necessary, redraw your Force Diagrams, so they are more to scale.arrow_forwardA 85 kg person stands on a scale. a.) What would be the scale readout? |N=[ mg (Express in Newtons, and as a multiple of the person's weight.) Now, find a general expression for the scale readout, in terms of the person's mass, acceleration, and/or g. Show that it can be used to get the answer for part a above, and then use it to get the answers for all of the following parts: b.) If the person stands on the scale in an elevator accelerating upwards at 1 m/s², what is the scale readout? |N=[ .mg (Does the person feel heavier or lighter than the "usual" of part a?) c.) If the person stands on the scale in an elevator accelerating downwards at 1 m/s², what is the scale readout? mg (Does the person feel heavier or lighter than usual?) d.) If the person stands on the scale in an elevator accelerating downwards at 9.8 m/s2, what is the scale readout? N= mg (Does the person feel heavier or lighter than usual?) e.) In parts b-d, was the actual weight of the person different? Explain the…arrow_forward
- In the space to the right of the figure sketch a force diagram for the cart on the table. Suppose that the hanging mass is 120g. Calculate the net force on the system. If the mass of the cart was increased but the hanging mass remained the same, how would the acceleration be affected? Explain how you know in terms of net force and system mass. If masses on the cart were moved from the cart to the hanger, how would the acceleration be affected? Explain how you know in terms of net force and system mass. For a system mass of 600 g and a hanging weight of .5 N, determine the acceleration of the system.arrow_forwardFor every problem, show FBDS and write down Newton's 2nd law in component form. Remember to be precise in your work: clearly describe what your system of interėst is, pay attention to vector/component notation, and follow a clear strategy in your work-the layout of your page should reflect a linear progression of steps and thoughts (please do not jolt down things all over the place!!); show all details of the calculations that are needed to answer the questions: no guesses of course! A block with mass M is pushed against a vertical wall with a force of magnitude P and directed at an angle 0 below the horizontal. The wall and the block experience friction (coefficient of static friction is Hs). Is it possible to keep the block from sliding downward? And if so, how exactly? Use Newton's 2nd law to support your answer. Marrow_forwardAnswer each question below using Newton’s second law. Explain your answers. (a) Two cars have the same net force acting on them, but one has more mass than the other.Which car will have the greater acceleration? (b) A heavy box of sand is on top of a cart. A person pulls the cart forward with a constant netforce while the sand leaks out of the box and onto the ground. What will happen to theacceleration of the cart?arrow_forward
- Complete the following paragraph by Identifying the terms. Drag and drop your answer/s into the provided box. By the end of the sixteenth century, the observation of the astronomical bodies had progressed to a remarkable degree. Tycho Brahe built the large observatory on an island near Copenhagen. Tycho painstakingly recorded precise observations of the motions of the planets using and After Tycho's death, Johannes Kepler studied his data and devise the three laws of planetary motion. The first law states that each planet moves along a/an with the sun at one focus. The second law says that the from the sun to a planet sweeps out equal areas in On the other, the third law says that the of a planet's orbital motion is proportional to the cube of its from the sun. :: mechanical gadgetry :: unaided eye :: telescope : elliptical path :: radius vector :: equal intervals of time square of the period :: mean distance :: areaarrow_forwardDirection: Solve the following problems.

- To be clear: You must write the words "Newton's Second Law" and point to an example of it within your solution! Write out the second law using symbols, not numbers. Writing "net force = m a" does not qualify because that could be written for any object. The symbols and subscripts should clearly refer to specific forces in each diagram. Examples, good and bad, of what might qualify are shown below. The following are three examples of Newton's second law written for an object called "E" (which is not in this question). Credit would be given for the first example but not for the second or third. This is a good example: mE g−TEJ sinθ1+NER cosθ2=mE a This is a bad example that is not specific enough: Σ FE=mE a This is a bad example with unspecified numbers and without symbols: (1.7 kg) g−(3.8 N) sin(59∘)+(4.9 N)cos(34∘)=(1.7 kg) a Once you have begun your solution with symbols in Newton's Second Law, you may begin to substitute numbers as needed.arrow_forwardDIRECTIONS: Solve the following problem.
