A flowerpot falls from a window sill 37.7 m
above the sidewalk.
What is the velocity of the flowerpot when
it strikes the ground? The acceleration of
gravity is 9.81 m/s2 .

Can you tell me the steps and why?

• Physics -

How much time does a passerby on the side-
walk below have to move out of the way before
the flowerpot hits the ground?

• Physics -

For the velocity, equation PE and KE.
PE=KE
mgh = (1/2)mv²
and solve for v.
(both g and h are negative, y is positive upwards)

For time, use
y=vi*t+(1/2)at²
for vi=0, equation simplifies to
y=(1/2)at²
(Notice that both y and g are negative)
