... Dy/dt = 10.2176 t – 7.7054 Evaluate at t= .4756 Dy/dt = -2.846 m/s If a ball was released from rest and fell 41cm before striking the lab table, how long would that fall take? T = sqrt (2 * h /g) = sqrt (2 *.41 /9.8) = 0.289 s If the initial velocity were 3.15 m/s, what would be the theoretical rang ...

Physics Midterm Study Guide
... The average velocity of any object is its displacement divided by the total time it took, including rest time. The length or shape of the path traveled, or changes in speed during the trip are not relevant. Its defining equation is v = Δx / Δt You should know and understand all of the above, and be ...

Centripetal Force
... Centripetal force is not another force to add to our list of forces such as weight, normal, etc. It is a characteristic of a force, force component, or combination of forces. For example, a bicycle rounding a flat curve will have a static force of friction maintain its circular motion. A bicycle rou ...
