A suspension bridge with weight uniformly distributed along its length has twin towers that extend 65 meters above the road surf
ace and are 1200 meters apart. The cables are parabolic in shape and are suspended from the tops of the towers. The cables touch the road surface at the center of the bridge. Find the height of the cables at a point 300 meters from the center. (Assume that the road is level.)
Average velocity is said to be equal to the instantaneous velocity when acceleration is zero. When acceleration of an object is equal to zero, there can be no change in speed or direction.
There is a flow of current from the battery's positive terminal, through the hobbyist's tongue to the battery's negative terminal. Energy is been transferred from the battery to the hobbyist's tongue by the current.
