- Given the acceleration as a function of the angle theta, a =6.5sinθ + 2.3cosθ. Find the optimal angle, so the acceleration is maximum Find the value of the maximum acceleration I have found the derivative of the function but am confusing myself on the next steps.Estimate the angle of vector A shown in the diagram below, to a range between adjacent multiples of 45°. Forexample, is it between 0° and 45°? 45° and 90°? 90° and 135°? And so on. Treat angles as between 0° and 360°,measured counterclockwise from +x direction. Estimate the angle of vector B, as well.I am not sure how to start these problems as I am given very limited information and am told that I have everything I need to complete them. We are given these equations as well to use for the problem.
- A car initially traveling eastward turns north by traveling in a circular path at uniform speed as shown in the figure below. The length of the arc ABC is 247 m, and the car completes the turn in 33.0 s. Need the answer for C in degree format not coordinates An x y coordinate axis is shown. Point A is located at a negative value on the y-axis, and an arrow points from point A to the right. A dotted line curves up and to the right in a quarter circle until it reaches point C on the positive x-axis. An arrow points directly upward from point C. Point B is on the dotted circle. A line drawn from the origin to point B makes an angle of 35.0° below the x-axis. (a) Determine the car's speed. ___________ (b) What is the magnitude and direction of the acceleration when the car is at point B? magnitude ___________ m/s2 direction _______________ ° counterclockwise from the +x-axisPlease help with the solution to this problem using (km/s). I know we will use Hohmann Transfer and a combined plane change. In the opening scene of the movie “Gravity” Dr Ryan Stone (Sandra Bullock) and Matt Kowalsky (George Clooney) are required to transit from the Hubble Space Telescope (Altitude 600 km, 28.5 degree inclination) to the International Space Station (Altitude 400 km, 51.6 degree inclination) using nothing but their Manned Maneuvering Units (MMU). An MMU has a delta V capability of about 30 m/s, and it would be impossible to perform this maneuver with so little delta V, but… a.) How much delta V would be required for this maneuver? b.) What if the maneuver did not require an inclination change (altitude change only?)Which of the following statements are correct? Adding two vectors creates a new "resultant" vector. When adding parallel vectors, the resultant vector is the sum of the magnitudes of the original vectors. When adding perpendicular vectors, the resultant vector is the sum of the magnitudes of the original vectors. Graphing calculators always report angles in degrees. Vectors pointing in different direction cannot be subtracted. A vector can be broken into x and y component vectors that sum to equal the original vector. Multiplying a vector by a scalar changes the vector's magnitude and direction.
- Can you answer problem 2? Can you also provide a short explanation for the answer you chose?The Maton family begins a vacation trip by driving 710 km west. Then the family drives 610 km south, 310 km east, and 410 km north. Where will the Matons end up in relation to their starting point? Give direction only, directly East is 0 degrees and the order goes counter clock wise (North is 90 degrees, West is 180 degrees, South is 270 degrees).A student walks 550 m [E], then 450 m [N30°W], and finally 350 m [S10°W]. Using the component method, find the resultant (total) displacement). Show your work and round your answer (magnitude and direction) to appropriate significant digits.
