Question #1016

A croissant is dropped from the top of the Eiffel Tower. The height of the tower is 300.5 meters (ignoring the antenna, and this figure changes slightly with temperature). Ignoring air resistance, at what speed will the croissant be traveling when it hits the ground?

Expert's answer

Time of free fall from the height h is:

0 = h - gt

t =√(2h/g) = √(2*300.5/9.8) = 7.83 s.

The speed would be

v= gt = 9.8* 7.83 = 76.83 m/s

0 = h - gt

^{2}/2;t =√(2h/g) = √(2*300.5/9.8) = 7.83 s.

The speed would be

v= gt = 9.8* 7.83 = 76.83 m/s
