Solve.A pebble is hurled upward from the top of a 1040-foot-tall building with an initial velocity of 
per second. Neglecting air resistance, the height h(t) in feet of the pebble after t seconds is given by the polynomial function h(t) = -16t2 + 128t + 1040a. Find the height of the pebble when t = 1.b. Find the height of the pebble when t = 6.4.
