The two ends of a length of chain are attached so that the chain makes a circle. If the chain is then spun very quickly, it can roll along the ground like a bicycle tire without crumpling. Consider the rolling chain shown in the figure. Assume the chain has uniform linear mass density μ and its center of mass moves to the right at a speed v0. (a) Determine the tension in the chain in terms of μ and v0. Assume the weight of an individual link is negligible compared to the tension. T = (b) If the loop rolls over a small bump, the resulting deformation of the chain causes two transverse pulses to propagate along the chain, one moving clockwise and one moving counterclockwise. What is the speed of the pulses traveling along the chain? (Use any variable or symbol stated above as necessary.) v = (c) Through what angle (in rad) does each pulse travel during the time interval over which the loop makes one revolution? (Assume the angle is measured clockwise from the ground. ) clockwise-traveling pulse rad counterclockwise-traveling pulse rad

When a camera flash goes off, the batteries immediately begin to recharge the flash's capacitor, which stores electric charge given by the following. Q(t) = Q0(1 − e−t/a) (The maximum charge capacity is Q0 and t is measured in seconds.) (a) Find the inverse of this function. t(Q) = Explain its meaning. This gives us the time t necessary to obtain a given charge Q. This gives us the time t with respect to the maximum charge capacity Q0. This gives us the charge Q obtained within a given time t. (b) How long does it take to recharge the capacitor to 77% of capacity if a = 5? (Round your answer to one decimal place.) sec

A 26 kg child is on a swing that hangs from 3.0 m long chains as shown in the figure below. What is her maximum speed if she swings out to a 45∘ angle? HINT: Remember that you want to use conservation of energy for this problem. What is special about maximum height? (Remember it's a turnaround point. ) There is a bit of geometry to do. You know how long the chains of the swing are, so how high above the lowest point is the seat of the swing when it is at its maximum height? Make sure to draw a picture and figure out the different lengths. What is the child's maximum speed? m/s
