After he gets the block to move, what does Dr. Hewitt do to drag the block across the table at a steady rate? View Available Hint(s)for Part A He applies a steadily increasing force. He applies a steadily decreasing force. He continues to apply a steady force. Part B If Dr. Hewitt applies 3 N of force to keep the block moving at a steady rate, what must be the force of friction, and why? View Available Hint(s)for Part B Equal to 3 N, because the force of friction should exactly balance out the force Dr. Hewitt applies, so that there is no net force acting on the block. Less than 3 N, because otherwise the block would not move forward. Dr. Hewitt applies a force of 3 N, so his force must overcome the force of friction. More than 3 N, because the force of friction is what prevents the block from accelerating due the force applied by Dr. Hewitt. So, it should overcome the force applied by Dr. Hewitt
