Question

If you could please do 1 and 2 

These problems share the same scenario. Each is just a different question
about the same situation. Also, note the magnitude of the gravitational
acceleration is 9.81 , not 9.80 as quoted in the text.
Consider a rock tossed upward at speed 33.45 from the top of the Empire State
Building (381 m above street level). It's given a little horizontal velocity that we'll
ignore just so it clears the building as it falls back down after reaching its maximum
height.
1) Calculate the time the rock spends on the way up to the maximum height.
A) 3.40979s
B) 3.409 795
C) 3.409 79s
D) 2.10676s
E) 2.10676s
F) 2.106 765
G) 5.6 7979 s
