You and a friend each drive 50.0 km. You travel at 85.0 km/h; your friend travels at 98.0 km/h. How long will your friend wait for you at the end of the trip?
The surfaces of the lens have radii of curvature 25.5 cm (located on the object side of the lens) and 51cm (located on the side opposite to the object side of the lens). What is the index of refraction, and the magnification of the lens?
An old oaken buck of mass 6.75 kg hangs in a well at the end of a rope. The rope passes over a frictionless pulley at the top of the well, and you pull horizontally on the end of the rope to raise the bucket slowly a distance of 4.00m.
