Q4) A thin rod of length L = 2.95 m and mass mrod= 2.18 kg can rotate around a fixed axis of rotation at one end of the rod (labelled by x in the figure). A point-like object of mass mb= 1.96 kg is moving horizontally until it strikes the bottom end of the rod and it is reflected horizontally in an elastic collision. L Text mb a) If the initial speed of the point-like object is v=7.42 m/s. What is the magnitude angular velocity of the rod right after the collision? (Hint: Use energy and angular momentum conservation to solve this problem) b) In this part the initial speed for the point like object is v = 14.2 m/s. What would the final speed of the point like object after the elastic collision be, if the mass of the rod is not the one given in part a) but instead is much heavier than the mass of the point like object?
