A rocket was launched vertically upward from a platform at a height of 8 feet. The initial speed of the rocket is 135 feet per second. Its height (in ft), relative to the ground, is defined by the equation h = 8 + 135t - 16t2, t seconds after it was launched. Calculate the rocket's height 4 seconds after it was launched.
