Follow the steps above to draw a pictorial representation of the following problem: A light train is traveling on a straight section of track at a constant speed of 15 m/s. As it approaches the next station, it starts to slow down at a rate of 5 m/s2 until it stops at the station. From the moment the train starts to slow down, how long does it take for the train to reach the station? Note that you are not...

TACTICS BOX 1.5 Drawing a pictorial representation
Draw a motion diagram. The motion diagram
develops your intuition for the motion and, especially important,
determines whether the signs of v? and
a? are positive or negative.
Establish a coordinate system. Select your axes
and origin to match the motion. For one-dimensional motion, you
want either the x axis or the y axis parallel to
the motion.
Sketch the situation. Not just any sketch. Show
the object at the beginning of the motion, at...

General Instructions: All of these problems rely on mathematical equations to describe velocity and acceleration fields. However, you should take some time looking at the equations for V to determine how velocity depends on x and y in each flowfield. For example, think about how u and v vary as x and y increase or decrease, or change from positive to negative. This ability to "vize"the flowfield will be very useful. Problem 1 your work and provide clear hand-written sample...

Please show all your work.
5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...

A cockroach named Cicero and a spider named Susan are playing
tag with each other. The “rightward" direction is taken as the
positive x-direction along the pipe. The following plot gives the
velocity versus time for bothCicero (solid line) and Susan (dotted
line).
We also happen to know that Cicero starts at the origin at time
t = 0, and Susan starts 9 cm to the left of Cicero. The period of
time depicted on the plot is divided into...

A student is riding their bike when they come across a turn in the form of a circular arc of radius R 3.0m as pictured in the diagram below and travel along this arc in the clockwise direction. At one point along this trajectory (the origin of the given coordinate system) it makes sense to define the Cartesian coordinate system shown where the x-axis is tangent to the trajectory and the y-axis is perpendicular to it. At this point the...
