Collars A andB slide along the fixed right-angle rods and are connected by a cord of length L = 6.9 m. Determine the acceleration of collar B when y = 2.3 m if collar A is given a constant upward velocity vĄ = 1.61 m/s. The acceleration of B is positive if to the right, negative if to the left. Answer: aB = i m/s2

To speed up the unrolling of a telephone cable the trailer with the reel of cable starts from rest and is given a constant acceleration of 2.1 ft/sec². Simultaneously, the tow truck pulls the free end of the cable horizontally in the opposite direction with a constant acceleration of 3.4 ft/sec². If both vehicles start from rest at the same instant, determine the magnitude of the total acceleration of point A on the forward end of the horizontal reel diameter (a) just as the motion starts and (b) at a time t = 1.5 sec after the start of the motion. 3.4 ft/sec² 1/9 2.7' A 2.1 ft/sec²

The drag racer P starts from rest at the start line S and then accelerates along the track. When it has traveled 120 m, its speed is 40 m/s and it is accelerating forward at 11.4 m/s². For that instant, determine the values of 7 and relative to axes fixed to an observer O in the grandstand G as shown. 26 m Answers: 7 = Ö = i i Hom P m/s² rad/s²

The air transport B is flying with a constant speed of 445 mi/hr in a horizontal arc of 9.1-mi radius. When B reaches the position shown, aircraft A, flying southwest at a constant speed of 310 mi/hr, crosses the radial line from B to the center of curvature C of its path. Write the vector expression, using the x-y axes attached to B, for the acceleration of A as measured by an observer in and turning with B.
