Help Particles q1 = -53.0 uc, q2 = +105 C, and q3 = -88.0 PC are in a line. Particles q1 and q2 are separated by 0.50 m and particles q2 and q3 are separated by 0.95 m. What is the net force on particle qı? Remember: Negative forces (-F) will point Left Positive forces (+F) will point Right -53.0 C -88.0 C 91 +105 pc +42 t 93 0.50 m 0.95 m​

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.)
