Question
A massive, custom-built sensor is dropped over the side of a building. Upon impact, it transmits its impact speed of 39.1 m/s just before it is very rapidly brought to a stop by its impact with the ground. How tall is the building? (Use 9.8 m/s2 as the value for the acceleration of gravity.) A massive, custom-built sensor is dropped over the side of a building. Upon impact, it transmits its impact speed of 39.1 m/s just before it is very rapidly brought to a stop by its impact with the ground. How tall is the building? (Use 9.8 m/s2 as the value for the acceleration of gravity.)Explanation / Answer
height of the building is H = v2 / 2g =(39.1)2 / (2*9.8)
= 78 meters
