Question 50

Multiple Choice

Solve.
-A pebble is hurled upward from the top of a 384 -foot-tall building with an initial velocity of 80 feet per second. Neglecting air resistance, the height $h ( t )$ in feet of the pebble after $t$ seconds is giv the polynomial function
$h ( t ) = - 16 t ^ { 2 } + 80 t + 384$
a. Find the height of the pebble when $t = 1$ .
b. Find the height of the pebble when $t = 3.7$ .
c. When will the pebble hit the ground?
