Homework Help: Batmobile physics problem

  1. Apr 26, 2004 #1
    hi, i am grade 12 student having difficulty on a question for my physics class. i was wondering if anybody could help me out.
    the question is:
    Batman drove the batmobile along a straight street in gotham city. He started from rest and maintained a constant value acceleration for 750m.Robin was standin on the floor of the batmobile holding the batrope, which was tied to the batmobile ceiling, when the trip began.the rope made a 30 degree angle with the verticle.even togh he picked his feet up off the floor the rope angle did not change. How long, in seconds, did the trip take?

    What acceleration would cause Robin's rope to make a 30 degree angle with the vertical?

    Here's a hint: Draw a triangle. Label what you know and solve for what you need.

    I'm thinking it would be a tan relationship.

    [tex]tan(\theta) = \frac{batmobile}{gravity}[/tex]
