The length of a simple pendulum is 0.85 m and the mass of the particle (the "bob") at the end of the cable is 0.22 kg. The pendulum is pulled away from its equilibrium position by an angle of 8.1∘ and released from rest. Assume that friction can be neglected and that the resulting oscillatory motion is simple harmonic motion. (a) What is the angular frequency of the motion? (b) Using the position of the bob at its lowest point as the reference level, determine the total mechanical energy of the pendulum as it swings back and forth. (c) What is the bob's speed as it passes through the lowest point of the swing? (a) Number Units (b) Number Units (c) Number Units

An object of mass m1 = 4.00 kg is tied to an object of mass m2 = 4.50 kg with String 1 of length ℓ = 0.500 m. The combination is swung in a vertical circular path on a second string, String 2, of length ℓ = 0.500 m. During the motion, the two strings are collinear at all times as shown in the figure. At the top of its motion, m2 is traveling at v = 5.00 m/s. (a) What is the tension in String 1 at this instant? N (b) What is the tension in String 2 at this instant? N (c) Which string will break first if the combination is rotated faster and faster? string 1 string 2

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?
