Question

Two stones of masses 2 kg and 5 kg are released from the top of a tower. Which stone will reach the ground first?

Answer 1

1. Since gravity works the same on all objects, both stones will reach the surface at the same time.
2. However, if one object's area is greater than the other, air resistance will be a factor. However, this is not the case here.
3. The free fall time is calculated as follows:

$\mathrm{t}=\sqrt{\frac{2\mathrm{h}}{\mathrm{g}}}$

Where, t is independent of mass. h and g are equal, both stones reach the ground at the same time.
