Hey guys, I needed help with this question:
I have no ideas on how to start, I know i have to use angular velocity/free body digrams, but the thing is, this is the only info that is given, nothing else. Could you please give some hints on how I can start this problem?
This is what I have done so far, although I can't really go ahead because the mass is unknown :(

Thank you!
An automobile traveling at 90 km/hr rounds a long sweeping curve of radius 250m. The air conditioner is on and the windows are rolled up so that the air within the car moves essentially as a rigid body. A child in the back seat is holding onto the string of a helium-filled balloon. On a straight road the string is vertical, but in the curve its not. Determine the magnitude and direction of the string angle as measured from the vertical.
