Using the following equation: x = (8P/9M)^1/2 * t^3/2, Draw a
graph of position vs time, when P=800W, P= 400W and P = 200W and M
= 1632.6kg. Also draw a graph of velocity vs time. Is this a
problem constant acceleration?
Draw a position-vs-time, velocity-vs-time, and
acceleration-vs-time graph for each of the following objects:
1. A car traveling in a straight line at a constant speed.
2. A ball rolling down a hill, getting faster as time goes
by.
3. A rock that is tossed straight up in the air before coming
back down to its starting point.
Draw a 1). position graph, 2). velocity graph, and 3). acceleration
graph of a person standing one second, then goes down into a squat
for three seconds, back up for one second and then a one second
stand for the first rep.
2nd rep- this person goes back down for three seconds, and
then has a one second pause at the bottom of the squat, and then
back up for one second.
2). A particle moving on the x-axis has a time-dependent
position (t) given by the equation x (t) = ct - bt^3. Where the
units of x are meters (m) and time t in seconds (s). (Hint: you
must get derivatives, you need graph paper)
(a) So that the position in x has units of meter which are the
units of the constants c and b?
If c = 5 and b = 1. From ti = 0s to tf...
A) Sketch the position vs. time graph for the following motion.
Starting at 0.5m from the detector, you moved away at a constant
velocity of 3 m/s for 2 seconds, then stood still for 1 second and
then walked toward the detector for 1 second at a velocity of 4m/s
after which you stood still for 3 seconds.
B) sketch the velocity vs. time graph for the above
description.
Let f(x)=(x^2+1)*(2x-3)
Find the equation of the line tangent to the graph of f(x) at
x=3.
Find the value(s) of x where the tangent line is horizontal.
From the following data, construct 3 graphs: [A] vs t, ln[A] vs
t, and 1/[A] vs t
a) determine the order of the reaction from the graphs.
b) from the one graph that is linear, determine the rate
constant, k.
You do not need to calculate the slopes of the nonlinear
graphs.
