Consider a ramp inclined at an angle theta. there is a disk rolling down the ramp (without slipping) which starts from rest at t=0. the wheel is a uniform disk with mass m and radius r. the coefficient of static friction is 'μ'. verify the work-energy theorem for the disk rolling down the ramp.

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.

Question 1 (5 pts): what is the maximum distance for which you can you resolve the two individual headlights of an on-coming truck as two separate lights rather than one if the headlights are separated by 2.00 m and your eye has a diameter of 1.00 centimeter? assume a wavelength of 500 nm.

Place me with this question is my last question
