To learn more, read your instructor's
First review Sections 2.1, 2.2, 2.3, 2.4, 2.5, and 2.6 of Young and Freedman,
the worked examples. You should then be able
to solve the problems given below.
that you are allowed only 6 answer attempts per problem.
Given Positions, Find Velocity and Acceleration
Given a table of position versus time, identify graphs of an object's trajectory, velocity, and acceleration.
To understand how to graph position, velocity, and acceleration of an object starting with a table of positions
The table shows the
coordinate of a moving object. The position is tabulated at 1-s intervals. The
coordinate is indicated
below each time. You should make the simplification that the acceleration of the object is bounded and contains no spikes.
Which graph best represents the function
, describing the
object's position vs. time?
Meaning of a bounded and nonspiky acceleration
A bounded and nonspiky acceleration results in a smooth graph of
Which of the following graphs best represents the function
describing the object's velocity as a function of time?
