(chatquestion)...8.01x Classical Mechanics: Problem Set 2 2. Accelerating Truck and Suspended Bucket A truck is traveling in a straight line on level ground, and is accelerating uniformly with an acceleration of magnitude a. A rope (that can be considered massless and inextensible) is tied to the back of the truck. The other end of the rope is tied to a bucket of mass M. The bucket tosses wildly when the truck starts to accelerate, but later on it stays at a fixed position at a fixed distance behind the truck, with the rope hanging straight at a fixed angle, as shown in the diagram. т (a) Find the angle 6 at which the rope will settle. Express your answers in terms of the given variables M, g, and a as needed. (b) What will the tension T of the rope be once it settles into this angle?
