Answer to Question #268527 in Physics for JINGJING

Question

At what velocity will this drop of dextrose hit the floor?

Answer 1

We can find the velocity from the kinematic equation:

$$v=v_0+gt=0+(-9.8\ \dfrac{m}{s^2}\times0.68\ s)=-6.7\ \dfrac{m}{s}.$$

The sign minus means that the velocity of the drop directed downward.
