Steven is doing interval training and runs at different paces throughout his workout. At times he runs at 0.5 m/s, other times he reaches a huge 3 m/s. If he begins his run at 0m and ends it at 1000m to the right, what is his average velocity if his run lasts a total of 500 seconds? Don't forget units and directions if appropriate.

If the area of a square has increased by a factor of 16, by how much has each side increased?

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.)
