Equations missing in the
given question. Based on standard question in the book, I am
solving this question as follows:
Kinmatic eqautions:
x(t)=xo + Vot +
(1/2)at^2
v(t)= Vo +
at
x(t)
is the position of the particle at a given instant of
time
xo is the initial position
v(t) is
the velocity of the particle at a given instant of
time
vo is the intial velocity of the
particle
a is the acceleration
(A) The quantity
represented by x is a function that changes over time
(i.e., is not constant).
TRUE (as the equation
includes the term t)
(B) The quantity
represented by xo is a function of time (i.e., is not
constant).
FALSE (as xo is
independent of t )
(C) The quantity
represented by Vo is a function of time (i.e., is not
constant).
FALSE (as initial
velocity is independent of t)
(D) The
quantity represented by v is a function of time (i.e., is
not constant).
TRUE (as the equation
includes t)
(E) A
particle moves with constant acceleration . The expression (
v(t)= Vo + at) represents the particle's velocity at what
instant in time.
Ans: when a time has passed since the beginning of the particle's
motion.
The quantity represented by is a function that changes over time (i.e., is not constant). Part...
Rotational motion with a constant nonzero acceleration is not uncommon in the world around us. For instance, many machines have spinning parts. When the machine is turned on or off, the spinning parts tend to change the rate of their rotation with virtually constant angular acceleration. Many introductory problems in rotational kinematics involve motion of a particle with constant, nonzero angular acceleration. The kinematic equations for such motion can be written as and . Here, the symbols are defined as...
(1) An object moves with constant acceleration 3.26 m/s and over a time interval reaches a final velocity of 10.8 m/s. a. If its initial velocity 5.39 m/s, what is its displacement during the time interval? Submit Answer Tries 0/10 b. What is the distance it travels during this interval? Submit Answer Tries 0/10 c. If its initial velocity is -5.39 m/s, what is its displacement during the time interval? Submit Answer Tries 0/10 d. What is the total distance...
dunal, But only over a part of the domain. The reason why it is useful to assume a local constant rate of change is because then the changes in the quantity's measures are proportional. In Problems 4 and 4, you assumed that the output quantity varies at a constant rate with respect to the input quantity, and used the proportionality in the changes in the quantity's measures to approximate the output values associated with particular input values. As you wi...
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...
Please help. (3) An automobile running on 4 wheels is about to pass over a speed bump that has a cross section that fits to a sine function of y(x)-5sinßx with B being a constant, and with a maximum width w 8 cm. as illustrated in Figure 1(a). The velocity of the automobile is 20 km/hr at the time of passing over the bump. The vehicle is supported by a suspension system that is consists of one coilover for each...
Assist ne please Question 3 NAME: The circuit shown below contains two switches which open and close perfectly out of phase with one another (only one is open at any given time, and once one closes the other immediately opens, and vice-versa). The switches alternate at a frequency of 10kHz, and each switch spends 50% of the time open and 50% of the time closed (ie, each switch is open for 100 microseconds and then closed for 100 microseconds). The...

part b and c In class we derived a Fokker-Planck equation for the velocity distribution P(et) starting from the assumption of small random changes in velocity at each time step f.(t) where f(t) is chosen from a distribution WU: ). Einstein's original approach to Brownian motion had a different starting point, focusing on position differences at each time step x(t + Δt)-x(t) + E(t) where £(t) is a random displacement chosen from some distribution W(E). Underlying this ap- proach is...
