As you take your leisurely tour through the solar system, you come across a 1.09 kg rock that was ejected from a collision of asteroids. Your spacecraft's momentum detector shows a value of 1.87 × 108 kg⋅m/s for this rock. What is the rock's speed? m/s rock's speed:

The graph shows the potential energy U of asystem as one object in the system moves along thex-axis and the rest of the system does not move.Six evenly-spaced points along the x-axis are labeled.At point H, the object is moving in the positivex-direction and the mechanical energy of the system is5.0 J. As the object moves, no energy enters or leavesthe system. Which of the following describes the magnitude ofthe momentum of the object in the first twostraight-line segments shown in the graph as theobject moves from point H to point J ?
