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?

The angular velocity of the disk in figure 1 is ω = 4t2 + 3 rad/s, where t is in seconds. (a) (2 points) What is angular velocity and the magnitude of the (linear) velocity of point A on the disk when t = 0.5 s. (b) (3 points) Let θ be the counter-clockwise angle of point A from the horizontal x-axis. The derivative of the angle of A is the angular velocity of A, i. e. dθ dt = ω. Integrate the angular velocity to get an expression for the angle, θ. Use the condition that at t = 0, θ = 0 to solve for the integration constant. (c) (3 points) Differentiate the angular velocity with respect to time to get an expression for the angular acceleration, α(t). (d) (2 points) What is the angular acceleration and the magnitude of the (linear) acceleration of point A at t = 0.5 s. Figure 1: Problem 2
