-
(3 points) The position of a particle as a function of time is given by
x(t) = Acos(wt) + bt + c
where A, w, b, and c are constants. Determine
the velocity and acceleration as functions of time.
-
(4 points) A drowsy cat spots a flowerpot that sails first up and then
down past an open window. The pot was in view for a total of 0.50
sec, and the top-to-bottom height of the window is 2.00 m. How high
above the window top did the flowerpot go? (Hint: Start by
making a diagram of the flowerpot going up and down, and overlay a window.
You will need to find two independent relations and use these to determine
two unknown constants.)
-
(3 points) A mass, M1, rests on an inclined plane, attached by a massless
rope over a frictionless pulley to a second mass, M2, as shown in the diagram
below. If the two masses are in equilibrium, and the plane is inclined
by an angle [theta], what is the mass M2, expressed in terms of M1 and
[theta]?
