A phone dropped at a height of 3600 ft. How many seconds will it take for the phone to hit the ground

the time of fall of the stone is 15 s.

Step-by-step explanation:

Given;

height through which the stone was dropped, h = 3,600 ft

the initial velocity of the stone, u = 0

The time of fall of the stone is calculated using the following kinematic equation;

h = ut + ¹/₂gt²

h = 0 + ¹/₂gt²

h = ¹/₂gt²

where;

g is acceleration due to gravity = 32.17 ft/s²

Therefore, the time of fall of the stone is 15 s.

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
