The distance (x) of an object from the top of a building after it has been dropped (where air resistance is negligible) can be found using the formula x ut

at 2 where u is the initial velocity of the object, t the time since the object has been dropped and a the acceleration due to gravity, which is approximately equal to -9.8 m/s2. When an object is dropped it has an initial velocity of 0 m/s, so the distance the object has fallen becomes x -4.9t 2. Using algebra, the distance from the building after t seconds can be found or the time taken to reach ground level could be calculated. If the object is instead dropped from a hot air balloon ascending at 10 m/s, the object ﬁrst travels in an upward direction. Its distance (x metres) above or below the height of the balloon from when the object is dropped can be found using x 10t 4.9t 2. Knowing the time taken for the object to reach the ground, we could again use algebra to ﬁnd factors, such as the height of the balloon, the greatest height reached by the object and the time taken for the object to return to the height it was released from.
