Problem 3. 1.5 m B PROBLEM 16.121 End A of the 6-kg uniform rod AB rests on the inclined surface, while end B is attached to a collar of negligible mass which can slide along the vertical rod shown. Knowing that the rod is released from rest when = 35° and neglecting the effect of friction, determine immediately after release (a) the angular acceleration of the rod, (b) the reaction at B. 25°

Problem 1. End A of the uniform 5-kg bar is pinned freely to the collar, which has an acceleration a = 4 m/s² along the fixed horizontal shaft. If the bar has a clockwise angular velocity @ = 2 rad/s as it swings past the vertical, determine the components of the force on the bar at A for this instant. Answers: Ax = 5 N, Ay = 57.1 N L X AO 0.8 m @ a

If v = (4t+5) m/s, where t is in seconds, determine a when t = 2 s. 2. If s = (2t³) m, where t is in seconds, determine v when t = 2 s. 3. If a = 2 m/s², determine v at s = 4 m if v = 3 m/s at s = 0. 4. If a = 4 m/s², determines when t = 3 s if v = 2 m/s and s = 2 m when t=0. 5. A particle moves along a straight line such that its position is defined by s = (t² - 6t + 5) m. Determine the average velocity, the average speed, and the acceleration of the particle when t = 6 s. 6. A particle is moving with a velocity of vo when s=0 and t=0. If it is subjected to a deceleration of a = -kv³ where k is a constant, determine its velocity and position as functions of time. 7. A particle travels along a straight-line path such that in 4s it moves from an initial position SA = -8 m to a position SB = +3 m. Then in…
