Question #1ee48
1 Answer
Given
(a) Here the collision is inelastic as KE is not conserved.
We are to proceed our calculation assuming that the collision is perfectly inelastic and the bodies of two player are entangled after collision.
Let the common velocity the players gained be v and its components along x-axis and y-axis are
Now applying the law of conservation of linear momentum along x-axis, we can write
Again applying the law of conservation of linear momentum along y-axis, we can write
(b) So the common velocity of the players
(c) Loss in mechanical energy
(d) This loss of mechanical will actually be transferred into equivalent amount of heat energy and will eventually be dissipated in the environment.
