1. The problem statement, all variables and given/known data A motion detector transmits a click which is reflected off of a moving car. The echo is received by the motion detector after .0026 seconds. the motion detector sends out a second click .1 seconds after the first click. The echo for the seconds click is received after .0031 seconds. 1) How far has the car moved? 2) What is the average velocity? 2. Relevant equations v = Vo + at S = 1/2 (Vo+V)t U = s/t S = vt 3. The attempt at a solution .0026 - .1 = .0974 seconds .0031 .0974 + .0031 = .1005 seconds 340 (Spd of sound m/s) * .1005 = 34.17 meters ?? Velocity ??
