Really need with these three similar physics questions as soon as !

1.) you are in paris, 60 m up in the eiffel tower. if you throw a euro downward at a velocity of 2.0 m/s, how long would it take the euro to hit the ground? neglect air resistance.

a. 3.3 s

b. 120 s

c. 41 s

d. 30. s

~~~

2.) a bicyclist passing through a city accelerates after he passes the signpost marking the city limits. his acceleration is constant at 6.0 m/s2. at time t1 = 0 s, he is at x1 = 7.0 m beyond the signpost and has a velocity v1 = 5.0 m/s.

find his position (distance from the signpost) 3 s after passing the signpost (at t = 3.0 s).

630 m
210 m
49 m
39 m
