Helicopter blades withstand tremendous stresses. In addition to supporting the weight of the helicopter, they are spun at rapid rates and experience large centripetal accelerations, especially at the tip. (a) Calculate the centripetal acceleration, in m/s, at the tip of a 3.70-meter-long helicopter blade that rotates at 310 rev/min. m/s? (b) Compare the tangential speed of the tip with the speed of sound (taken to be 340 m/s on this day). V V sound

1. 2. Draw a picture to represent this problem and show all work. A rope is being used to pull a rather large Christmas tree from your car to your house. The rope exerts a force of 83 pounds on the tree, and it makes an angle of 28° with the ground. Find the work done in moving the Christmas tree the 122 straight- line feet to your house. Round to the nearest unit and write your answer on the line provided. 1. Draw a picture to represent the problem. Show all work. You are left without a car after a party, and you must pull one of your "tipsy" friends home to your dorm room in a wagon that a friend let you borrow for the trip. A force of 117 pounds is made on the handle pulling the wagon up a hill that has an incline of 3.4° just in front of the dorm. Find the work done in moving the wagon the final 19 feet up the hill if the handle makes a 32° angle to a horizontal with the ground. Round to the nearest unit and write your answer on the line provided. 2.
