Phys-1010q - lecture 5 - forces & acceleration (ch. Our two course assistants are chloe herrera and zhanna rhodnova. Ca office hours on wednesday and thursday at 4:00pm. Next week: room pb 302a (pb = physics building) Professor wells will not be here on monday and wednesday. Going to washington d. c. to defend funding! You see a mouse running along a straight line path across your kitchen floor. Using the infrared range finder, you record the position of the mouse relative to where it first appeared from behind the kitchen cabinet at time t=0s. = 5 cm/s (cid:1005) v1-2 = (cid:1005)(cid:1004) (cid:1009) . The biggest problem here is getting confused between position, velocity, and acceleration. You need to divide two positions by time to get velocity. You need to divide two velocities by time to get acceleration. In first second, v1 = 5 m/s . From t=1 to 2, v2 = (10-5)m / 1s = 5 m/s .
