SOLUTION: an objects altitude in meter, is given by the polynomial h+ vt-9.8t^2, where h is the height in meters from which the launch occurs, v is the initial upward speed in meters per sec

Question 225214: an objects altitude in meter, is given by the polynomial h+ vt-9.8t^2, where h is the height in meters from which the launch occurs, v is the initial upward speed in meters per second and t is the number of seconds for which the rocket is airborne. a pebble is shot upward from the top of a building 164 tall. if the intial speed is 36 meters per second, how high above the ground will the pebble be after 3 seconds. round results to the nearest tenth of a meter.

Given the intial equation and the constants, we can simply plug them in:

Solving this yields:

This height is in addition to the 164 meters of the building, so

The pebble is 183.8 m above the ground at .
