Question

A china dish falls from a height of 1.5 m above the floor. Calculate its velocity just before it

reaches the ground. (ag = - g= -9.8 m/s^2) *

Answer 1

12m/s

Step-by-step explanation:

v^2=u^2+2as

v=?

u=0 (the dish was stationary before it fell)

a=9.81 m/s^2 (acceleration due to gravity/freefall)

s=1.5m (the drop height)

So: v^2=0+2.9.81.1.5 = 144.35415

and therefore v=sqrt 144.35415

12x12=144 so I'd say v=12m/s
