An airplane is flying in a horizontal circle at a speed of 490 km/h. If its wings are tilted at 44° to the horizontal, what is the radius of the circle in which the plane is flying? Assume that the required force is procided entirely by an "aerodynamic lift" that...

A sphere of mass 3.3 10-4 kg is suspended from a cord. A steady horizontal breeze pushes the sphere so that the cord makes an angle of 41° with the vertical when at rest (a) Find the magnitude of that push. (b) Find the tension in the cord.

algebra
yes since you x value is positive the graph opens upwards, and all absolute value graphs have a distinct V shape, using the vertical line test you can see that it is a function

While exploring a cave, a spelunker starts at the entrance and moves the following distances: 75.0 m north, 250 m east, 210 m at an angle 30.0° north of east, and 150 m south. Find the resultant displacement from the cave entrance. I know I have to use the formulas Ax = A ...
