The speed of sound at room temperature (20 degrees celsius) is 343 m/s. if the speed of sound in air increases about 0.60 m/s for every 1 degrees celsius increase, what is the temperature when the speed of sound is 353 m/s?

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

Porque crees que el agua no podia subir mas de 10 m de altura con ese tipo de bomba

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
