(13%) Problem 2: You are hiking along a trail in a wide, dry canyon where the outdoor temperature is T = 26.5° C. To determine how far you are away from the canyon wall you yell "Hello" and hear the echo t = 2.8 s later. Randomized Variables. T=26.5° C 1=288 33% Part (a) Calculate the speed of sound in the valley in meters per second, assuming the speed at 0° C is 330 m/s. y= sin() cotan() atan() cosh() cos() asin() acotan() tanh() Degrees O Radians Hints: 0% deduction per hint.
