us 15 (20%) Problem 1: You are hiking along a trail in a wide, dry canyon where the outdoor temperature is T=25.5° C. To determine how far you are away from the canyon wall you yell "Hello" and hear the echo t=2.7 s later. Randomized Variables T=25.5°C t=2.7s 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. cos() sin( tan() л ( cotan() asin() acos() E atan() acotan() sinh) tanh() cosh() O Degrees cotanh() Radians Submit Hint 7 8 4 5 1 2 0 9 BONK 6 3 .
