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?
