Q. A 2.1 x 10^3 kg car starts from rest at the top of a driveway that's sloped at an angle of 20.0 degrees with the horizontal. An avg. friction force of 4.0 x 10^3 impedes the cars motion so that the cars speed at the bottom of the driveway is 3.8m/s. What is the length of the driveway?

Q. An astronaut in a satellite says she can just barely resolve two point sources on the Earth, 110.0 km below. Assume λ=540.0 nm, and the pupil diameter of the astronaut's eye to be 5.20 mm.
