Question
On a velocity-time graph for a particle, suppose the plot starts at some positive velocity and then follows a straight line to zero at a later time. Which of the following must be true about a position vs. time graph for this same time interval? The curve will start at a positive position value and follow a straight line to zero at the later time. The curve will rise steeply at first and as time goes on will level out approaching its highest position value at the later time. The curve will drop steeply at first and as time goes on will approach its lowest position value at the later time The curve will start at the zero of position and follow a straight line to its highest position at the later time. A thrown stone hits a window but doesn't break it. Instead, it reverses direction and ends up on the ground below the window. In this case, we know: the force of the stone on the glass > the force of the glass on the stone. the force of the stone on the glass = the force of the glass on the stone. the force of the stone on the glassExplanation / Answer
