Object B is at rest when object A collides with it. The collision is one-dimensional and elastic. After the collision object B has half the velocity that i object A had before the collision By how much is the mass of object B greater than that of object A? Express your answer numerically as a ratio of the mass of object B to the mass of object A. mg MA Submit Part C VT ΑΣΦ Request Answer PAR A if the velocity of object A before the collision was 6.0 m/s to the right, what is its velocity after the collision? 4 Express your answer with the appropriate units. Enter positive value if after the collision object A is moving in the same direction as before the collision, and negative value if object A is moving in a direction opposite to its original direction. 20 ? Units Constant ?
