S. A cart attached to a spring is displaced from equilibrium and then released. There is no friction. A graph of displacement as a
function of time for the cart is shown. The arrows and signs above the cart indicate the positive and negative directions for the
position of the cart.
(a) At which point or points is the acceleration positive?
(b) At which point or points does the cart have zero velocity but
nonzero net force?
A Displacement, cm
(c) At which point or points is the net force on the cart equal to zero?
A
16
Time
(d) At which point or points are the acceleration, velocity, and
displacement all positive? _
(e) At which point or points is the acceleration nonzero and opposite in sign to the position?
(f) At which point or points is the velocity nonzero and opposite in sign to the acceleration?
(b) At which point or points is the kinetic energy equal to zero?
(e) At which point or points is the kinetic energy positive?
(c) At which point or points is the total energy at its maximum value? _

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?
