- Problem 9: A runner is at the starting line and hears the starting gun. He starts running from rest with a constant acceleration a; = 0.51 m/s. He crosses the finish line V V, at d = 100 m and then begins slowing down. It takes him a time interval t. to cross the V = 0 finish line. It takes him a time interval t = 6.5 s to return to rest after crossing the finish line. Use the given coordinate system where x is positive to the right. Refer to the figure. t= 0 t=t =t, Part (a) Enter an sion for the time, t, it takes for the runner to cross the finish line, in terms of d and a;. Expression : tr = Select from the variables below to write your expression. Note that all variables may not be required. a, B, A, Q, 0, a¡, d, g, h, i, j, k, 1, m, P Part (b) Enter an expression for the runner's speed, v,, when he crosses the finish line, in terms of a; and t, only. Expression : r = Select from the variables below to write your expression. Note that all variables may not be required. B, T, Q, 0,…4. An observer is standing on the platform of a railway station. A train goes through the station without stopping. If the frequency of the train whistle decreases by a factor of 1/4 as it approaches and then passes him, calculate the speed of the train (assume the speed of sound in air = 343 m/s).1. A person holds a rifle horizontally and fires at a target. The bullet has a muzzle speed of 180 m/s, and the person hears the bullet strike the target 1.20 s after firing it.

Your best friend Clark is a storm chaser and heads to the center of the storm to take some readings while you stay dry at home. While Clark is at the center of the storm, he sees and hears lightning strike a tree that is 185 m from where he is standing. You are 134 km from the tree. How long does it take for the sound to reach Clark? Assume the speed of sound is 343 m/s. How long does it take for the light to reach you?During a thunderstorm, 3.0 s elapses between observing a lightning flash and hearing the resulting thunder. Approximately how far away in kilometers and miles was the lightning flash? (Assume the speed of sound is 344 m/s.) km mi

Two identical loudspeakers are located at points (-10,0,0) and (0,0, 10) of our coor- dinate system, where the numbers in the brac- kets correspond to the (r, y, z) coordinates of the points, expressed in meters. The loudspeakers are driven by the same oscillator with a frequ- ency of 170 Hz. The speed of sound in air can be considered 340 m/s. a) Give the coordinates of those points loca- ted on the positive r axis where the sound waves coming from the two loudspeakers interfere con- structively. b) A receiver is started to move slowly from the origin (0,0,0) along a path lying in the r-y plane so that it receives constant sound intensity throughout its slow motion. What is the shape of the path the receiver should take?
