The world's largest refracting telescope is operated at the Yerkes Observatory in Wisconsin. It has an objective of diameter of 1.02 m
Suppose such an instrument could be mounted on a spy satellite at an elevation of 300. km above the surface of the Earth. What is the minimum separation of two objects on the ground if their images are to be clearly resolved by this lens? (Assume an average wavelength of 0.55 ?m for white light.)

In the figure, a stunt car driver negotiates the frictionless track shown in such a way that the car is barely in contact with the track at the top of the loop
The radius of the track is 9.9 m and the mass of the car is 1800 kg. Find the magnitude of the force of the car on the track when the car is at point A. You can treat the car as a point mass. What will be an ideal response?
