PHYS 212 Study Guide - Midterm Guide: Retrograde And Prograde Motion, Electric Field, Bundesautobahn 81
Document Summary
Mars has a radius 3. 41 x 106m and a mass of 6. 42 x 1023kg. A metal rod is to be dropped through the field as shown. Page 1: the diagram shows the electric field lines in a region of space containing two small charged spheres (y and z). What was this feature: that the orbits were ellipses, the period of the planets, the monthly planetary phases, retrograde motion, a car traveling at 30 mi/hr strikes another stationary car of similar mass from the rear. The two cars have their bumpers lock together as a result of the collision. What is the resulting speed of the two cars after the collision: 30 mi/hr, 45 mi/hr, 15 mi/hr, 20 mi/hr. Page 2: a rock strikes a block of wood in two different scenarios. In the first case the rock bounces off of the wood and in the second case the rock becomes stuck in the wood.
