A piece of glass dropped near the top of the hotel falling 215 meters. Ignoring air resistance, how long would it take the piece of glass to hit the wall

Answer 1

Walls are vertical and the glass will never strike a wall since the gravity vector is vertical as well. However, if we wish to know how long the glass takes to fall 215m to the ground the relationship of 1/2 g t^2 applies in the absence of aerodynamic forces and initial velocity =0. Thus t = sqrt(2h/g)= 6.62 seconds
