A physics student decides to calculate how long it would take a penny to fall from
the Eiffel tower, 324 m. How long should it take for the penny to hit the ground, neglecting air

Without drag force the penny will cover a distance of D = 1/2 gT^2 and take T = sqrt(2D/g) seconds to do it. So T = sqrt(2*324/9.8) = 8.13 seconds. ANS.
