Marble M moves to the right before it strikes marble N, which is initially at rest. Both marbles have the same mass, 4.1 g. After the collision, the marbles move in the directions shown in the diagram. Marble M moves away from the collision point with a speed of 23.9 cm/s.
What is the initial kinetic energy of marble M?
A) 6.1 × 103 g . cm/s2
B) 7.2 × 103 g . cm/s2
C) 8.3 × 103 g . cm/s2
D) 9.4 × 103 g . cm/s2
