an object is dropped from a bridge to the water below. with a stopwatch, an observer notes that it takes 10 seconds for the object to travel the distance from the bridge deck to the water below. Determine the height of the bridge from the water, the velocity, and the acceleration of the object just as it hits the water. NOTE: solve this provlem in metric units and US customary units
