In a physics lab experiment, a compressed spring launches a 30 g metal ball at a 35° angle. Compressing the spring 18 cm causes the ball to hit the floor 2.0 m below the point at which it leaves the spring after traveling 6.0 m horizontally. Part A What is the spring constant? Express your answer with the appropriate units. ▸ View Available Hint(s) ī Submit μÀ k= Value Units ?

Part A The two spheres A and B each have a mass of 400 g. The spheres are fixed to the horizontal rods as shown in (Figure 1) and their initial velocity is 2 m/s. The mass of the supporting frame is negligible and it is free to rotate. Neglect the size of the spheres. If a couple moment of M = 0.9 N m is applied to the frame, determine the speed of the spheres in 3 s. Express your answer to three significant figures and include the appropriate units.

In the following, you will solve two variations of this problem. In both variations, we will assume that the ant is walking on a paper that rests on a table, and then suddenly the sheet of paper starts moving. Make sure to model your work based upon what is provided here. Namely, make sure that you include a description of your coordinate system, that you represent any velocity vectors in terms of components, and that any velocity vectors. you relate (a) In the first variation, we want to find the velocity vector for the ant relative to the paper that would result in the ant traveling due east at 2 miles per hour relative to the table. The paper is still going to move due southeast at v2 mi/hr.

Please solve thanks
