Question

A car accelerates forward in a straight lin with acceleration a. A fuzzy die hangs on a string from the rear view mirror.

a) derive an expression for the angle with which the string supporting the fuzzy die will make with the vertical

b) what would a have to be in order to make the die tilt by 30 degrees from vertical

The same car is being driven i a circular path of radius R with constant speed v

c) derive an expression for the angle with which the string supporting the fuzzy die will make with the vertical

d) what would v have to be in the case that R= 50m and the die tilts by 30 degrees from vertical
