With the initial speed of the particle as 4.0 m/s and changing at the rate of 5.0 m/s2, the magnitude of the total angular displacement (in revolutions) of the particle after a time interval of 2 s is nearly?If the rigid body rotates 30deg about the global X-axis and the origin of the body translates to (X, Y, Z)=(500, 0 600), the final point in the Global frame is (500 -100, 773.2). Find the origin position (x1, y1, z1) in the body coordinate frame by using the inverse 4X4 matrix.Consider the Atwood machine, where two masses m1 = 12.6 kg and m2 = 4.2 kg are connected by an ideal wire that passes through a pulley of mass M = E of radius R = 0.15 m. The pulley is attached, but can rotate freely around its axis of symmetry. As shown in the Figure below, at the initial instant the mass m1 is at a height h= 3.29 m in relation to m2. Knowing that the system starts from rest, and that the magnitude of the linear velocity of m1 when the masses pass through the same vertical position is v=3.31 m/s, what is the mass M of the pulley? Here, assume the acceleration due to gravity as g=10 m/s², the pulley moment of inertia as I=MR2 and, finally, that the wire does not slide on the pulley. Choose one: a. 4,2 kg b. 14,7 kg c. 10,5 kg d. 6,3 kg e. 12,6 kg f. 16,8 kg g. 8,4 kg h. None of the other alternatives.
