A. 1 m/s B. -1 m/s C. 2 m/s D. -2 m/s E. 3 m/s t x s m s s m m t x v AD 1 0 30 30 0 = = = What are the velocities of runner A and runner B respectively, if vectors point right are positive and vectors pointing left are negative? A. +6 mph and +5 mph B. -6 mph and +5 mph C. 6 mph and -5 mph D. -6 mph and -5 mph E. Not enough information Clicker Quiz 3-2 E N Runner A is running with a constant velocity of 6.0 mi/h due east. Runner B is running with a constant velocity of 5.0 mi/h due west. If both runners start at the same time and meet at point x and runner A takes time t A to reach point x and runner B takes time t B to reach the same point x, then: 1. t A > t B 2. t A = t B 3. t A <t B 4. t A = 1 s 5. Not enough information Runner A is initially 4.0 mi west of a flagpole and is running with a constant velocity of 6.0 mi/h due east. Runner B is initially 3.0 mi east of the flagpole and is running with a constant velocity of 5.0
