Answer:
0.79 sec
Step-by-step explanation:
Given there is a tool at the top of the building which is dropped by a worker and it follows the following equation at every instant of time .

where 
We know that this height is measured from the base of the building which means that when the tool reaches the bottom of the building it has h = 0 feet.
Let this be done at time t
h(t) = 0



t = 0.79 sec
Therefore the total time taken by the tool to reach the bottom of the building is 0.79 sec.
The answer is 45 when you substitute all the variables in

Mercury travels a distance of 153 461 500 kilometers on its orbit.
<h3>How much distance did Mercury travel on its orbit?</h3>
The statement indicates that Mercury has a <em>circular</em> orbit and indicates the <em>central</em> angle covered by translation. The distance traveled is found by definition of <em>circular</em> arc:
s = (2.65 rad) · (57 910 000 km)
s = 153 461 500 km
Please notice that the radius of translation is the distance from the Sun to Mercury.
Mercury travels a distance of 153 461 500 kilometers on its orbit.
