The weight of the mirror and the slickness of the floor cause the mirror to slip. If @ is the angle between the top of the mirror and the wall and y is the distance from the floor to the top of the mirror, what is the rate of change of y with respect to 0? (Use symbolic notation and fractions where needed.) dy do ft/radian How fast is the top of the mirror slipping down the wall when 0 = $? (Use decimal notation. Give your answer to three decimal places.) dy ft/radian "=#1 OPQuestion 24 of 25 > Attempt 2 A simple pendulum is a small-sized ball swinging from a light string. As it swings, the supporting string makes angle 0 with the vertical. See the figure. T, tension W. weight At an angle 0, the tension in the string is T = W cos(0), where W is the weight of the swinging ball. Find the rate of change of the tension T with respect to 0 when the pendulum is at its highest point (0 = 0max). (Use symbolic notation and fractions where needed. Enter max as a if needed. ) -W(a) do 10=max Incorrect Find the rate of change of the tension T with respect to 0 when the pendulum is at its lowest point.
