A stone is dropped from a high tower and 9.21 seconds later it hits the ground. How high is the tower?

S = 415.64m

Explanation:

Given the following data;

Time, t = 9.21secs

Since it's a free fall, acceleration due to gravity = 9.8m/s²

Initial velocity, u = 0

To find the height of the tower, we would use the second equation of motion;

Where;

Substituting into the equation, we have;

Height, S = 415.64m

Therefore, the tower is 415.64m in height.

answer; /// the above statement is (true);

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
