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-axis

A plane leaves Seattle, flies 85.0 mimi at 20.0 ∘∘ north of east, and then changes direction to 51.0 ∘∘ south of east. After flying at 125 mimi in this new direction, the pilot must make an emergency landing on a field. The Seattle airport facility dispatches a rescue crew. A.) In what direction should the crew fly to go directly to the field? Use components to solve this problem. B.) How far should the crew fly to go directly to the field? Use components to solve this problem.
