Suppose you catch a baseball and then someone invites you to catch a bowling ball with either the same momentum or the same kinetic energy as the baseball. Which would you choose? Explain.

Solution 2DQ The momentum of a body is given by p = mv , where m is the mass of the body and v is the speed. 1 2 The kinetic energy of the body is given by K = m2 Let the mass of the baseball be m and its speed be v. So, its momentum p = mv Kinetic energy k = mv 2 2 Let the mass of the bowling ball be M and let its velocity be V. So, its momentum P = MV 2 Kinetic energy K = MV2 Momentum: Given, mv = MV m V Therefore, the speed of the baseball is more than that of...
