Question

An object with a mass of 8 kg is dropped and takes 5 s to hit the ground. Then another object with a mass of 16 kg is dropped from the same point. If a 200 kg object is dropped from the same point, how long will it take to hit the ground?

Answer 1

In Physics, all objects fall at the same rate in a vacuum. Therefore, both the 16 kg and 200 kg objects will take 5 seconds to hit the ground when dropped from the same height as an 8 kg object did.

Step-by-step explanation:

The subject of the question is Physics, more specifically, it relates to the concept of free fall under the influence of gravity, which is a core topic in classical mechanics. According to the principles of Physics, the acceleration due to gravity is constant (9.8 m/s2 on Earth), and in the absence of air resistance, all objects will fall at the same rate regardless of their mass. Thus, if an object of 8 kg takes 5 seconds to hit the ground when dropped, any other objects dropped from the same height will also take 5 seconds to hit the ground, as their mass does not affect the time it takes to fall. This means that both the 16 kg and the 200 kg objects will take 5 seconds to reach the ground when dropped from the same point as the 8 kg object.
