Aconstruction worker drops a hammer from a height of 25 m.
how long will it take the hammer to hit the ground?
use the formula  , where is the initial velocity and is the initial height.
round to the nearest tenth of a second. enter your answer in the box.

2.3 seconds

Step-by-step explanation:

Given: A construction worker drops a hammer from a height of .

Using formula , where is the initial velocity and is the initial height.

Put t=0, the initial velocity = 0m/s in the beginning.

When the hammer hits the ground, then height

 [Since time is a positive quantity.]

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

a is the correct
