Which describes how the spring constant affects the potential energy of an object for a given displacement from an equilibrium
position?
The higher the spring constant, the greater the gravitational potential energy.
The lower the spring constant, the greater the gravitational potential energy.
The higher the spring constant, the greater the elastic potential energy.
The lower the spring constant, the greater the elastic potential energy.

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)
