Question

How long will it take a drop of dextrose from a bottle 2.30 m high hit the floor?

Answer 1

We can find the time that the drop of dextrose takes to fall from the height of 2.30 meters as follows:

$$h=\dfrac{1}{2}gt^2,$$ $$t=\sqrt{\dfrac{2h}{g}}=\sqrt{\dfrac{2\times2.30\ m}{9.8\ \dfrac{m}{s^2}}}=0.68\ s.$$
