A child of mass m is sitting at rest on a swing of length L. Their parent pulls them back making an angle of θ with the vertical as shown in the diagram. The parent uses a force that is perfectly horizontal. a) Find an expression for the force required to pull the child back as a function of the angle made by the swing. θ, m, L, and any fundamental can be in your answer. b) (Calculus version) i. Set up but do not solve an integral that could be used to calculate the work done on the child. ii. Now execute the integral showing that the work done will equal the resulting increase in potential energy. c) (Non calculus version) i. Find an expression for the height of the child above their lowest position as a function of θ and L. ii. Find an expression for the potential energy of the child in terms of m, θ, L, and any fundamental constants. d) The child is released and swings down to the lowest position. i. What is the tension in the cable the instant they are released? (Hint: their velocity the instant they are released is zero, but the net force is unbalanced. ) ii. What is the acceleration of the child the instant the parent releases them? iii. What is the speed of the child at the bottom of their swing? iv. What is the tension in the cable at the bottom of their swing?

A box is on a rough surface that is inclined at an angle of 30.0∘ to the horizontal. A mass, m1 = 0.270 kg, is attached to a hanging mass of m2 = 105 g over an ideal pulley. a. Draw two free-body diagrams, one for each mass, showing all forces acting on them and chosen direction of motion. b. What is the value of μ that allows the block to slide down the incline at constant speed? Blank 1 c. The incline is then greased to remove the friction and the masses released again from rest. Find the tension in the string, in Newtons, Blank 2 and the acceleration of the box, in m/s2. Blank 3 d. How long, in seconds, does it take the box to slide a distance of 1.40 m along the incline? Blank 4 For this problem, SHOW ALL WORK including a free-body diagram of forces on each mass shown in the drawing below. The direction of accelerations should be clearly indicated on the sketch. Show all equations used before entering numbers. This problem should be well-structured. DO NOT ENTER UNITS WITH ANSWERS.

A box (mass m ) is released from rest and slides down an inclined rough surface. The friction interaction results in an increase in thermal energy of the two surfaces (box and incline) of Efric ( > 0). The incline of height H makes an angle θ with respect to the horizontal. This problem should be solved using energy methods, not F→net = ma→. A. [6 pts] Find a symbolic expression for the speed of the block when it gets to the bottom of the incline, vbot. Your answer should be in terms of the given quantities m, H, θ, Efric and constants. Some symbols may not be needed. B. [2 pts] D. Does your result make sense if the height of the incline is larger/smaller? "Yes" or "No" is not sufficient. Explain the behavior you expect and whether your result shows that. C. [2 pts] Does your result make sense if there is no friction? "Yes" or "No" is not sufficient. Explain the behavior you expect and whether your result shows that.
