4 pts Question 7 KE KE The graph in the upper left in red and black above shows the velocity v of an object on the y-axis as a function of time t on the x-axis. We do not have a graph of the linear momentum of the graph of the upper left, but which of the graphs of Kinetic Energy versus time on the right would need to be inverted around the time (x-axis) to represent the graph of the linear momentum vs time? O Graph a Graph c O Graph d O Graph b
