Suppose that you look into a photometer's eyepiece and the fluorescent disks appear to be equal in intensity. If the distance between the photometer to lamp 1 is 400mm, the distance between the photometer to lamp 2 is 200 mm, and the intensity of lamp 2 is known to be 15 candelas, what is the intensity to lamp 1?

Big commercial airplanes are sometimes pushed to an area by a tractor. A 1800-kg tractor exerts a force of 1.75x 104 N backward on the pavement, and the system experiences forces resisting motion that total 2400 N. Calculate the force exerted by the tractor on the airplane, assuming 2200 N of the friction is experienced by the airplane and the acceleration is 0.15 m/s2.
