Q1. The coefficient of static friction between the 3000 lb car's tires and the road is 0.5. Determine the steepest grade the car can drive up at constant speed if car has (a) rear=wheel drive; (b) front-wheel drive; (c) four wheel drive.
Q2. A solid disk of radius R is composed of two different materials. For r < R/2, the material is one-third as dense as the remaining outer part with r > R/2. Work out the moment of inertia about an axis through the center and perpendicular to the disk, expressed solely in terms of the total mass M and radius R.

Light from a He-Ne laser (= 632.8) strikes a pair of slits at normal incidence, forming a double-slit interference pattern on a screen located 1.10 from the slits. The figure shows the interference pattern observed on the screen.
A screen is placed 42.7 cm from a single slit that is illuminated with light of wavelength 677 nm. If the distance between the first and third minima in the diffraction pattern is 3.45 mm, what is the width of the slit.
