A flowerpot falls off a window sill and falls past the window below. It takes 0.5 s to pass through a 2.0 m high window. Find how high is the window sill from the top of the window?
Text Solution
Verified by ExpertsThe correct answer is:
C
h = ut + 1/2 at 2
or 2.0 = u(.5) + 5(1/4)
or u = 1.5 ms -1 .
Using v 2 – u 2 = 2gh.
h = 1.5 2 /2 × 10 = 2.25/20 = 0.125 m = 12.5 cm.
