Solve the all parts of given question:
Question: Dana has a 0.75-kg sports medal suspended by a long ribbon from her rearview mirror. As she accelerates onto the highway, she notices that the medal is hanging at an angle of 7o from the vertical.
Part A: What is the tension in the medal's ribbon?
Part B: What is her car's acceleration?
I need help to calculate the tension in the medal's ribbon.
