In science and engineering, the weight<span> of an object is usually taken to be the force on the object due to gravity. It is calculated by multiplying the mass with the gravitational acceleration.
W = mg = 1700 (9.81) = 16677 N
Hope this answers the question. Have a nice day.</span>
Let 
be the height of the building and thus the initial height of the ball. The ball's altitude at time 
is given by
where 
is the acceleration due to gravity.
The ball reaches the ground when 
after 
. Solve for :
so the building is about 16 m tall (keeping track of significant digits).
Answer:
B is the best answer for the question
