The answer is b no problem
Answer:
t = 3.29 seconds
Explanation:
It is given that,
Height of the Eiffel tower is 60 m
Initial speed of a euro, u = 2 m/s
It will move under the action of gravity in the downward direction. Firstly, we can find the final velocity as follows :

Let t is the time taken by the euro to hit the ground. It can be calculated as :

Hence, it will take 3.29 seconds to hit the ground.
