A flower pot falls off a window sill and falls past the window below. It takes 0.30s to pass a window 3.45 m high. How far is the top of the window below upper window sill?

A flower pot falls off a window sill and falls past the window below.

1.	A flower pot falls off a window sill and falls past the window below. It takes 0.30s to pass a window 3.45 m high. How far is the top of the window below upper window sill?
Answer» <html><body><p>ime = t = 0.30 sDistance = S =3.45 mTo find:h =?Explanation:Let h be the height window sill from the ground.An object is following down from the window.∴ a = g =9.81Now, the object is following down from 3.45 m <a href="https://interviewquestions.tuteehub.com/tag/high-479925" style="font-weight:bold;" target="_blank" title="Click to know more about HIGH">HIGH</a> from the ground.By using the <a href="https://interviewquestions.tuteehub.com/tag/third-1414358" style="font-weight:bold;" target="_blank" title="Click to know more about THIRD">THIRD</a> law of kinematical <a href="https://interviewquestions.tuteehub.com/tag/equations-452536" style="font-weight:bold;" target="_blank" title="Click to know more about EQUATIONS">EQUATIONS</a> = ut + 3.45 = u (0.30) + 0.5 × 9.81 ×0.30 × 0.30u = 25.8924∴ u = 25.89 m\sNow consider the object is following down from the window sill.v = 0 , s = h = ?By the third law of kinematics:0 = 25.89 × 25.89 + 2 × 9.81 × <a href="https://interviewquestions.tuteehub.com/tag/hh-1019999" style="font-weight:bold;" target="_blank" title="Click to know more about HH">HH</a> = -34.16 mA negative sign shows that object is following down to the ground.∴ h = 34.16 mA window sill is 34.16 m high from the ground.</p></body></html>
