So the length of the string is 42cm long and the distance from the floor of the bus to the package is 50cm. What does it mean when it says "found to hang at rest relative to the bus"?

As your bus rounds a flat curve at constant speed, a package with mass 0.300kg, suspended from the luggage compartment of the bus by a string 42.0cm long, is found to hang at rest relative to the bus, with the string making an angle of 30.0o with the vertical. In this position, the package is...

Thank you guys so much for helping me out!

I got the answer right! Ok this is how I approached it: I know f= ma where a is acceleration, which is v^2/r I know static friction is f=(mu)N where N is m*g therefore: (mu)m*g=m*v^2/r m's cancel out leaving: (mu)r*g = v^2

I can understand I need to find centripetal acceleration (by the way, is that the same as radial acceleration?) so I use a= v2/r, right? But how can I use this equation if my speed is constant? Also for friction, it's Fs= \musN where N is Newtons. Are these the equations I need to use? Do I...
