You threw a box full of your ex's things with dimensions of 0.15lm] X 0.25[In] X O.30[m]. [t oated along a lake with the broadest face facing down. The box is submerged to a height of 0.05[m]. What is the mass of the piece of box? The density of water is 1000[kg/1n3]. After doing all the work, Leni got tired and suddenly lost grip on the string. The 1000M] box slid down from the top of the inclined plane and collided to the other 1000M box. The inclined plane has a surface length of 3.0[m] that makes a 30.0\" angle with respect to the ground. After the collision, the two boxes stuck and moved together with the same speed. Then, the boxes ran into an unstretched spring with a force constant 4000mm]. Assuming that the surfaces are frictionless, nd the maximmn distance of the compression of the spring 'om the equilibrium position. A 1.50lkg] box moves along a frictionless horizontal surface with an initial speed of 5.00[:n1/s] going to the right. A constant 3.00[N] force is then applied to the box at an angle 9 = 35.0\" with respect to the displacement vector. What is its nal speed after moving 2.00[m|? Consider the following composite body as shown. The composite body is made up of uniform rods each of mass M and 1 2 length L. The moment of inertia of each rod through its center of mass and perpendicular to its length is'l'3m _ EM'L What is the moment of inertia of the composite object when it is allowed to rotate about the Y axis as shown? Assume that the Y axis is exactly in the middle of the composite body. Choose the answer below: 1 r 2 AJMLZ C.ML2B.ML2D.%SML2
