The height, h, in feet, of an object dropped from the top of the Empire State Building can be estimated using the equation h= -16t^2+1,454, where t is the time

Question

I couldn't fit my whole question so here it is: The height, h, in feet, of an object dropped from the top of the Empire State Building can be estimated using the equation h= -16t^2 + 1,454, where t is the time in seconds after the object is dropped. What is the best estimate for how far above the ground will the object be after 8 seconds? 

 

 

The choices are: 1,390 feet

                               1,326 feet

                               512 feet

                                430 feet

Answer 1

Substitute t=8 into the equation.

 

h = -16(8)² + 1454

h = -16(64) + 1454

h = -1024 + 1454

h = 430

 

Pick the answer choice that matches or comes close to the calculated number.
