Calculate the force, in newtons, exerted by each of the 10 braces if a strong wind exerts a horizontal force of 660 n on each square meter of the wall. assume that the net force from the wind acts at a height halfway up the wall and that all braces exert equal forces parallel to their lengths. neglect the thickness of the wall.

What is the approximate amplitude of this wave a.10 seconds b.15 centimeters c.30 centimeters d.15 seconds

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
