PSQ5. A light, rigid rod is 77.0 cm long. Its top end is pivoted on a frictionless, horizontal axle. The rod hangs straight down at rest with a small, massive ball (1.00 kg) attached to its bottom end. You strike the ball, suddenly giving it a horizontal velocity so that it swings around in a full circle. What minimum speed at the bottom is required to make the ball go over the top of the circle? (a) determine the minimum energy of the ball at the top choose your answer... (b) determine the minimum energy of the ball at the bottom of the circle choose your answer... that is required to make the ball go over the top of the circle. (c) Find the ball's minimum speed required at the bottom of the circle choose your answer... ? tips: $W_{F_t} = 0$ --> isolated system (ball-Earth) --> energy is conserved: $\Delta E_k + \Delta E_g = 0$ minimum speed at the bottom --> zero speed at the top

8 5 points Why did James Madison oppose the inclusion of a list of individual rights in the Constitution? Multiple Choice He was afraid the listing of such rights would bring an end to slavery. He believed the act of listing such rights would limit them in practice. He did not believe in the concept of individual rights before a federal government. He doubted that the states could ever agree on a specific list of rights. He worried it would limit the power of the federal government too severely.

week 9 time at 25:00 The second phasor term on the right side of Eq. (8-7), $ E_{0}^{-} e^{j k z} $ represent a cosinusoidal wave traveling in the $ -z $ direction with the same velocity $ u_{p} $ If we are concerned only with the wave traveling in the $ +z $ direction, we set $ E_{0}^{-} a=0 $. However, if there are discontinuities in the medium, reflected waves traveling in the opposite direction must also be considered. The associated magnetic field $ \boldsymbol{H} $ can be found from the $ \boldsymbol{\nabla} \times \boldsymbol{E} $ equation: \[ \mathbf{\nabla} \times \mathbf{E}=\left|\begin{array}{lll} \mathbf{a}_{x} & \mathbf{a}_{y} & \mathbf{a}_{z} \\ 0 & 0 & \frac{\partial}{\partial z} \\ E_{x}^{+}(z) & 0 & 0 \end{array}\right|=-j \omega \mu_{1}\left(\mathbf{a}_{x} H_{x}^{+}+\mathbf{a}_{y} H_{y}^{+}+\mathbf{a}_{z} H_{z}^{+}\right), \] which leads to \[ \begin{aligned} H_{x}^{+} & =0 \\ H_{y}^{+} & =\frac{1}{-j \omega \mu} \frac{\partial E_{x}^{+}(z)}{\partial z} \\ H_{z}^{+} & =0 \end{aligned} \] \[ \begin{array}{l} (8-12 b) \\ (8-12 c) \end{array} \] Thus $ \mathrm{H}_{y}^{+} $is the only nonzero component of $ \mathbf{H} $; and since Eq. (8-12b) yields \[ \frac{\partial E_{x}^{+}(z)}{\partial z}=\frac{\partial}{\partial z}\left(E_{0}^{+} e^{-j k_{0} z}\right)=-j k_{1} E_{x}^{+}(z), \] \[ H_{y}^{+}(z)=\frac{k_{1}}{\omega \mu} E_{x}^{+}(z)=\frac{1}{\eta} E_{x}^{+}(z) \quad(\mathrm{A} / \mathrm{m}) . \] We have introduced a new quantity, $ \eta $, in Eq. (8-13): \[ \eta=\sqrt{\frac{\mu}{\epsilon}} \] which is called the intrinsic impedance of the medium. In air: \[ \eta_{0}=\sqrt{\frac{\mu_{0}}{\epsilon_{0}}} \cong 120 \pi \cong 377 \] $ (\Omega) $

Problem: 7 (of 30) Do not round intermediate answers. Give your final answer(s) to three decimal places. Check your units. A jet transport with a landing speed of 220 km/hr reduces its speed to 60 km/hr with a negative thrust R from its jet thrust reversers in a distance of 405 m along the runway with constant deceleration. The total mass of the aircraft is 135 Mg with mass center at G. Compute the reaction $N$ under the nose wheel B toward the end of the braking interval and prior to the application of mechanical braking. At the lower speed, aerodynamic forces on the aircraft are small and may be neglected. N = kN
