Final answer:
To determine the altitude of an object moving at a certain speed, we need additional information such as time or initial height. However, using an example, we can calculate the altitude when a boulder breaks loose from a 250 m high cliff and determine the time a tourist has to get out of the way after hearing the sound of the rock breaking loose.
Step-by-step explanation:
To determine the altitude of an object moving at a certain speed, we need additional information such as the time it takes to travel or the initial height of the object. Without this information, we cannot calculate the altitude directly.
However, I can provide you with an example related to altitude and velocity. Suppose a boulder breaks loose from a cliff that is 250 m high. The acceleration due to gravity is approximately 9.8 m/s². Using the equations of motion, we can determine the velocity at which the boulder strikes the ground. Let's assume there is no initial velocity. The formula to calculate the final velocity is given by v = √(2gh), where v is the velocity, g is the acceleration due to gravity, and h is the height. Substituting the values, we get v = √(2 × 9.8 × 250) ≈ 98 m/s.
Regarding the second part of your question, to determine how long a tourist at the bottom has to get out of the way after hearing the sound of the rock breaking loose, we can use the speed of sound as the distance traveled during the time it takes for the sound to reach the tourist. Let's assume a reaction time of 0.300 seconds. The distance traveled by sound is given by d = speed × time. Substituting the values, we get d = 335 × 0.300 = 100.5 m. Therefore, the tourist would have approximately 100.5 meters divided by the speed of sound to get out of the way.
