- 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.

Briefly describe the difference between elastic and inelastic collisions and give an example of each. Describe these collisions in terms of the kinetic energy and momentum. 4. A moving object collides with and sticks to a stationary object. Do the combined objects move slower, faster or at the same speed as the original moving object? 5.

- The block's displacement (or change in position) in reference frame R during the period AL * is either upward, downward, or equal to zero? Explain. (Use the velocity arrow from section c.i. to guide your response.) Does the block have an upward, downward, or no net force? Explain. Use the acceleration arrow from section c.i. to help you answer this question: Is the net force doing more work on the block than it is taking off? Explain. Based on your responses to the preceding two questions, how would you answer this question? Test to see whether you've answered section c.iii correctly in terms of net force work done on the block.arrow_forwardProblems 1. A particle of mass m has an initial momentum vector p, = mv, as shown. After being given a sharp blow, the particle has a final momentum vector p, = mv,. Draw on the figure a vector representing the impulse J that must have been delivered to the particle by the sharp blow. Explain your reasoning. 2° mv 1 mv2arrow_forwarda.) If an object is already moving and you applied another force parallel to it and with the same direction, does this mean that another counter force will be generated? Explain. b.) Considering question (a), what if you applied a force lower than the force of momentum (and gravity, etc.) on the object, will it generate a counter force? Explain. c.) On our activity, pushing the object at rest generates a counter force. How is this?arrow_forward
- Two objects have a perfectly elastic collision, as exactly illustrated in the diagram below. The first object (red ball) comes in at some initial speed and strikes the second one (blue ball), which was initially stationary in our reference frame. What is the speed of the blue ball after the collision? Write your answer as a fraction of v1. In other words, if you get v2 = 0.20v1, just enter 0.20. All we know is the proportionality of the masses and the relative speed of the first ball before and after the collision.arrow_forwardConsider the discrete-time system given below and answer the following questions. y[n] = 0.6x[n] + 0.35x[n-3] + 0.05x[n-5] a.
