What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

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.)
