Question: An arrow is shot from a height of 1.3 m toward a cliff of height H. It is shot with a velocity of 31 m/s at an angle of 60° above the horizontal. It lands on the top edge of the cliff 3.4 s later.
(a) What is the height of the cliff (in m)? m
(b) What is the maximum height (in m) reached by the arrow along its trajectory? m
(c) What is the arrow's impact speed (in m/s) just before hitting the cliff? m/s
