Gunther needs a 75% concentrated solution. When making his solution at room temperature, he could only make a solution that was 70% before the solute settled out.

What could he do to make his solution reach 75%?

Put the solution in an ice bath, dissolve the solute, and let it return to room temperature.

Heat the solution, dissolve the solute, and let it cool verifying nothing settled out.

Add more water, boil the solution, and dissolve the solute until the some of the water evaporates.

Keep the solution at room temperature, add more water, and dissolve the excess solute.

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.)
