So, the acceleration due to gravity is taken as positive. g = +9.8 ms-2 When a body is thrown vertically upwards its velocity is decreasing. So, the acceleration due to gravity is taken as negative. g = -9.8 ms-2 Numericals Question 1. To estimate the height of the bridge over a river, a stone is dropped freely in the river from the bridge. The stone takes 2 seconds to touch the water surface in the river. Calculate the height of the bridge from water level. . Disclaimer: "This video is for educational and informational purposes only and is not intended to infringe on any copyrights.
