Question

A bird drops a nut from a height of 441 feet. Its height, h, in feet is given by the equation h=-16t^2=441 where t is the time in seconds the nut has fallen. How many seconds will it take for the nut to hit the ground?

Answer 1

A bird drops a nut from a height of 441 feet.
Its height, h, in feet is given by the equation h=-16t^2=441
,where t is the time in seconds the nut has fallen.

The time it will it take for the nut to hit the ground is given as:


`t^(2) = (441)/(16) \\ \\ t = (21)/(4) \\ \\ t = 5.25 seconds`
