A 300N uniform rectangular sign 4m w is suspended from a horizontal, 5m-long rod, so that the sign's right edge is lined up with the rods right end. The w of the rod is 80N. The left end of the rod is supported by a hin ge and the right end is supported by a t cable making a 20 angle with the horizontal, as shown in the picture. Find the te nsion in the cable, and the horizontal and vertical components of force exerted on the left end of the rod by the h ing

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
