An aircraft undergoes two displacements. if the first displacement is directed at an angle of 210° with the positive x axis and has magnitude 32.0 miles, and if the resultant displacement is directed at an angle of 70.0° with the positive x axis and magnitude 32.0 miles, what are the magnitude and direction of the second displacement? (both angles are measured counterclockwise from the +x axis.) g

One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. you see that the patch of light seems to be a circular diffraction pattern. it appears that the central maximum is about 1 cm across and you estimate that the distance from the window shade to the wall is about 3 m. what is (a) the average wavelength of sunlight? (b) the diameter of the pinhole?

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
