Question

A bowling ball is dropped off the top of the Eiffel Tower. If the Eiffel Tower is 300 meters

high and we neglect air resistance, how long does it take for the ball to hit the ground?
5.33 s
C
15.3 s
07.82 s

Answer 1

7.82 s

Step-by-step explanation:

Given:

Δy = 300 m

v₀ = 0 m/s

a = 9.8 m/s²

Find: t

Δy = v₀ t + ½ at²

(300 m) = (0 m/s) t + ½ (9.8 m/s²) t²

t = 7.82 s
