Unformatted text preview: Announcement Due to an accident, Prof. Kleinman will be unable to teach this PHY302K course. I have been asked by the Chairman, Prof. Hazeltine, to teach the remaining part of the course. Instructor: L. Frommhold, RLM 10.324; 471 5100 email: frommhold@physics.utexas.edu office hours: MWF 1111:50 a.m. at RLM 10.324 Grading: On a scale of 100, an A requires 90 or more points; B for 75 points or better; C for 50 points or better; the minimally revised 1stday handout will be posted. c circlecopyrt L.Frommhold . p.12/12 OneDimensional Kinematic Eq.s For constant acceleration a position x versus time t is x = x ( t ) = x + v x t + 1 2 a x t 2 and velocity v x versus time is v x = v x ( t ) = v x + a x t You can eliminate t by combining these equations v 2 x = v 2 x + 2 a x ( x x ) How does that look in two dimensions? c circlecopyrt L.Frommhold . p.11/12 TwoDimensional Kinematic Eq.s For constant acceleration vector a position vector r = { x ( t ); y ( t...
