QuestionTwo suitcases, one and one , are dropped. Which hits the ground first with no wind resistance?
Studdy Solution
STEP 1
Assumptions1. The mass of the first suitcase is7 kg. The mass of the second suitcase is12 kg3. Both suitcases are dropped from the same height at the same time4. There is no wind resistance5. The acceleration due to gravity is constant for both suitcases
STEP 2
According to the law of gravity, all objects near the earth's surface fall with a constant acceleration, regardless of their mass. This is known as the principle of equivalence.
STEP 3
The time it takes for an object to fall from a certain height is given by the equationwhere- is the time it takes for the object to hit the ground, - is the height from which the object is dropped, and- is the acceleration due to gravity.
STEP 4
Since both suitcases are dropped from the same height and there is no wind resistance, the time it takes for each suitcase to hit the ground is the same, regardless of their masses.
STEP 5
Therefore, the correct answer isc. The suitcases will hit the ground at the same time.
