A 60.0 Kg boy and a 40.0 kg girl engage in a tug of war on a n icy frictionless surface. If the acceleration of the girl is 3.0 m/s^2, determine the acceleration of the boy. (Use the Newton’s 3rd law of motion)

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?

Distinguish between linear momentum and angular momentum
