Hickman was constructed in 1927 on the country estate of Missouri legislator and educator David Henry Hickman, next to what was then U.S. Route 40. The school was built to replace the earlier Columbia High School and carried over many of its traditions including the mascot and yearbook.
Average Velocity, General. The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time. If the beginning and ending velocities for this motion are known, and the acceleration is constant, the average velocity can also be expressed as.
Speed is the distance an object travels per unit of time. Speed can be expressed as kilometers per hour (km/hr), meters per second (m/s), and so on. In most cases, objects donât travel at a constant speed. Therefore, the average speed is used to describe the motion. s = speed, t = time, and d = distance. Acceleration is the rate at which an objectâs speed changes. Acceleration can be expressed as meters per second per second (m/s/s or m/s2). Forces such as gravity, air resistance, and friction can cause an object to decelerate (decrease speed over time).
