Chapt. 2 One-Dimensional Kinematics 17 002 qmult 00250 1 1 5 easy memory: timeless equation 21. The constant-acceleration kinematic equation without the time variable (which can be called the timeless equation for mnemonic reasons) is: a) v 2 = v 2 0 2 a Δ x . b) v = v 0 + 2 a Δ x . c) v 2 = v 2 0 + 2 a/ Δ x . d) v 2 = v 2 0 + a Δ x e) v 2 = v 2 0 + 2 a Δ x . 002 qmult 00310 1 3 3 easy math: d=vt calculation Extra keywords: physci 22. You move at speed 3 m / s. How far do you go in 9 s? 002 qmult 00320 1 1 3 easy math: travel time from distance/speed: Knoxville 1 Extra keywords: physci 23. You have just traveled the back roads from Knoxville to Nashville. Your average speed was 60 mi / h, but you occasionally hit an instantaneous speed of 130 mi / h. (Could be you’re hauling white lightning.) Your odometer travel distance is 250 miles. How long have you been on the road? 002 qmult 00322 1 3 2 easy math: average speed on round trip: Knoxville 2 Extra keywords: a round trip to Knoxville
