when you take a bowling ball and drop it at a height of about 3,000 feet * 34 feet above the weather area how long would it take for the bowling ball to touch the ground and what would the bowling balls mass be when it feel ad when it hit the ground?

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.)
