Question

An object is dropped from the top of a tower with a height of 1180 feet. Neglecting air​ resistance, the height of the object at time t seconds is given by the polynomial -16t^2 + 1180. Find the height of the object at t=8 seconds.

The height of the object at 8 seconds is __ feet.

Answer 1

156 ft

Put 8 where t is, and do the arithmetic.

-16·8² +1180 = -1024 +1180 = 156

The height of the object at 8 seconds is 156 feet.
