Aroller-coaster car has a mass of 1200 kg when fully
loaded with passengers. as the car passes over the top of a circular
hill of radius 18 m, its speed is not changing. at the top of the
hill, what are the (a) magnitude fn and (b) direction (up or
down) of the normal force on the car from the track if the car’s
speed is v 11 m/s? what are (c) fn and (d) the direction if v
14 m/s?

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.)
