Acar traveling at 60 km/h will skid 30 m when its brakes are locked. if the same car is traveling at 180 km/h, what will be the skidding distance? be sure to show all work to support your answer.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
