9 1 point 11 Pulleys C and D in Figure are fastened together. Weights A and B are supported by ropes wound around the pulleys as shown. The radius for pulley C is 188 mm and the radius for pulley D is 138 mm. If weight A is accelerating downward at 3.3 m/s, determine the angular acceleration of pulleys C and D. Provide your answer in rad/s and round to the nearest one decimal place. A x -mm rad y-mm rad 1 point B Pulleys C and D in Figure are fastened together. Weights A and B are supported by ropes wound around the pulleys as shown. The radius for pulley C is 187 mm and the radius for pulley D is 136 mm. If weight A is accelerating downward at 6.2 m/s, determine the linear acceleration of weight B. Provide your answer in m/s and round to the nearest two decimal places. A x-mm rad y-mm rad 13 1 point A train with a maximum speed of 105 km/h has an acceleration rate of 0.22 m/s and a deceleration rate of 0.24 m/s. If the train covers 1500 m while accelerating to maximum speed from rest, how long does this take? Provide your answer in s and round to one decimal place. 15 1 point A train with a maximum speed of 105 km/h has an acceleration rate of 0.78 m/s and a deceleration rate of 0.58 m/s. If the train takes 50 s to slow down from maximum speed to a complete stop, how much distance does it cover during this process? Provide your answer in m and round to the nearest whole number.
