An arrow is shot from a height of 1.7 m toward a cliff of height H. It is shot with a velocity of 32 m/s at an angle of 60° above the horizontal. It lands on the top edge of the cliff 3.8 s later.

What is the height of the cliff (in m)?

34.55m

What is the maximum height (in m) reached by the arrow along its trajectory?

40.88m

What is the arrow's impact speed (in m/s) just before hitting the cliff?

???

I just need to know C.
