A stopper holds block A so that block A and block C do not move initially. Suddenly, the stopper is removed, and block C moves down with a constant acceleration. After block A has moved 1.5 m, a speed of block A is measured to be 0.6 m/s. Determine the change of position of block B at the moment.

Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car Pobserves this speed via radar. The driver of car A is traveling at VA = 138 km/h as it passes P, but over the next 4.3 seconds, the car uniformly decelerates to the speed limit of 100 km/h, and after that the speed limit is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 5.0 m/s² until a speed of 167 km/h is achieved, and that speed is then maintained. Determine the distances required for the police officer to overtake car A. Answer: s= i m

The two cars A and B travel along the circular path at constant speeds VA = 80 ft/s and VB = 100 ft/s, respectively. If they are at the positions shown when t= 0, determine the time when the cars are side by side, and the time when they are 90° apart.

A helicopter starts from rest at point A and travels along the straight-line path with a constant acceleration a. If the speed v = 32 m/s when the altitude of the helicopter is h = 38 m, determine the values of r, r, 0, and 0 as measured by the tracking device at O. At this instant, 0 = 43°, and the distance d = 182 m. Neglect the small height of the tracking device above the ground. Answers: !!! = = X = i i i i ע Th m/s m/s² rad/s rad/s² A
