Test Your Understanding: A police officer pulls over a motorist and states that the motorist was going faster than the highway speed limit. The motorist states that the speed limit is 60 miles per hour, that he left home at
4:00 PM, that he traveled 120 miles, and that it is exactly 6:00 PM right now. The officer still gave the motorist
the ticket, and the charge still held up in court. In a brief paragraph, explain the argument that the motorist was
making in your own words, and explain what argument the officer made in court that caused the charge to hold
up.

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
