Both girls arrive at the same time at opposite sides of a door that can swing open in both directions. Without either of them knowing that someone is on the other side, Carly pushes with a force of 1,000-N at a 60° angle 40-cm from the hinge, while Delaney pushes perpendicularly with a force of 650-N 65-cm from the hinge. In which direction does the door open? Demonstrate and explain.

Question
Both girls arrive at the same time at opposite sides of a door that can swing open in both directions. Without either of them knowing that someone is on the other side, Carly pushes with a force of 1,000-N at a 60° angle 40-cm from the hinge, while Delaney pushes perpendicularly with a force of 650-N 65-cm from the hinge. In which direction does the door open? Demonstrate and explain.
Expert Solution
Step 1
