Would anybody like to join my particle physics/Quantum Mechanics class? This is not a class for just smart kids. Anybody can be good in physics. If you would like to join just go to google classroom and type in 3deqwfn for the class code. I do hope to see you all there. Thank you dearly

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.)
