Le Problem 3.3 The motion of a particle is defined by the equations x=(4cos -2) (2 - cos act) and y =(3 sin TI)/(2 - cos al), where x and y are expressed in feet and / is expressed in seconds. Show that the path of the particle is part of the ellipse shown, and determine the velocity when (a) / -0. (b)/ 1/3 s, (c) 1 = 1 s.
6. [20 points] The following nonlinear differential equations describe the motion of a body in orbit around two much heavier bodies. An example would be an Apollo capsule in an Earth-moon orbit. The three bodies determine a two-dimensional Cartesian plane in space The origin is at the center of mass of the two heavy bodies, the r-axis is the line through these two bodies, and the distance between their centers is taken as the unit. Thus, if μ is the...
1) Figure 5.2-1 shows the free body diagrams and the resulting equations of motion that are found by applying Newton's second law of motion to the Atwood's machine. From the equations of motion shown in the figure, derive equations (5.2) and (5.3). (Hint: Think two equations and two unknowns.) 2) Consider an Atwood's machine with m, =(110. 00.1) g and m, = (175. 00.1) g. Determine the acceleration of the masses.

Equations of Motion: Translation Learning Goal: To use the equations of motion as they relate to linear translation of an object to determine characteristics about its motion. The car shown has a mass of m= 1200 kg and a center of mass located at G. The coefficient of static friction between the wheels and the road is us 0.240. The dimensions are a = 1.05 m. b= 1.65 m, and c= -0.350 m Assume the car starts from rest, the...
