An arrow is shot from a height of 1.95 m toward a cliff of height h. it is shot with a velocity of 29 m/s at an angle of 60â° above the horizontal. it lands on the top edge of the cliff 3.8 s later.
a) what is the height of the cliff (in m)?
(b) what is the maximum height (in m) reached by the arrow along its trajectory?
(c) what is the arrow's impact speed (in m/s) just before hitting the cliff?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
