Question

You accidentally slide a glass of orange juice off a table that is 1.1 m tall. How long does it take the juice to hit the ground

Answer 1

First write down all the known variables:

d = -1.1m

a = -9.8m/s^2

vi = 0m/s

t = ?

Now use the kinematic equation that relates all the variables:

d = vi*t + (1/2)at^2

(-1.1) = (0)t + (1/2)(-9.8)t^2

-1.1 = -4.9t^2

0.22445 = t^2

0.47s = t

It takes 0.47 seconds for the juice to reach the ground.
