A policeman chases a master jewel thief across city rooftops.They are both running at 5 m/s when they come to a gap between buildings that is 4 m wide and has a drop of 3 m .The thief,having studied a little physics,leaps at 5 m/s and at 45'and clears the gap easily.The policeman did not study physics and thinks he should maximize his horizontal velocity,so he leaps at 5 m/s horizontally.(a)Does he clear the gap?(b)By how much does the thief clear the gap? • A policeman chases a master jewel thief across city rooftops. They are both running at 5 m/s when they come to a gap between buildings that is 4 m wide and has a drop of 3 m .The thief, having studied a little physics, leaps at 5 m/s and at 45◦ and clears the gap easily. The policeman did not study physics and thinks he should maximize his horizontal velocity, so he leaps at 5 m/s horizontally. (a) Does he clear the gap? (b) By how much does the thief clear the gap?
