An object, initially at rest, is accelerated by a constant force. Which graphs show the variation with
seed of the obiect?
time t of the kinetic energy and the variation with time t of the speed of the object?
Graph 1:
The graph of kinetic energy vs. time would start at 0 and increase linearly with time until it reaches a maximum value. The graph of speed vs. time would also start at 0 and increase linearly with time until it levels off at a constant speed.
Graph 2:
The graph of kinetic energy vs. time would start at 0 and increase quadratically with time. The graph of speed vs. time would start at 0 and increase linearly with time.
Graph 3:
The graph of kinetic energy vs. time would start at 0 and increase linearly with time until it reaches a maximum value. The graph of speed vs. time would start at 0 and increase exponentially with time.
