Question
Please give the reason why you choose the option.
MC 12 A block is slid along a horizontal surface so that it will collide with another stationary block that has a different mass, as in the diagram to the right. The block with the greater mass is labeled with a capital "M, " while the block with lesser mass is labeled with a lower-case "m." Prior to the experiment, the blocks were prepared for one of three kinds of collision: elastic (KE conserved), inelastic (thermal energy created), or spring-loaded (a latched spring between the blocks is unloaded upon collision, pushing the blocks apart). In the collision shown to the right, the incoming block stops moving after the collision as the target block moves off. The velocity vectors drawn are not to scale - i.e. you cannot conclude anything about their relative magnitudes from the diagram. In which manner were the blocks prepped for this collision to occur? elastic inelastic spring-loaded Internal forces don't affect the result of a collision, so this result occurs for all three preparations. Internal forces don't affect the result of a collision, but this result can never occur for any preparation.Explanation / Answer
a) for elastic,
block will stop only when both are of same mass.
but that is not case hence it can not be elastic.
b) for inelastic collision,
both blocks will move togther and that is also not the case.
c) in spring loaded case, block M will to the left after collision,
hence Ans (e)
