An object is dropped from the top of a tower. If it takes 4s for it to reach the ground, calculate the height of the tower.(g = 10 ms‾², ignore air resistance) By: Sunday|Published on: Jan 26|Categories: Physics WAEC| 0 comments A. 20m B. 40m C. 80m D. 160m Correct Answer: Option C C. 80m Explanation H = ½gt² ½×10×4²=80 Users Also Read These:A body is projected vertically upwards with a speed…A stone of mass 1kg is dropped from a height of 10m…If it takes an object 3s to fall freely to the…An object of mass 0.25kg moves at a height h above…An object is released from rest at a height of 25m.…SEE ALSO A plane inclined at 30o to the horizontal has an efficiency of 50%.
