4. A stone is thrown at an angle of 30.0° above the horizontal from the top edge of a cliff with an initial speed of 12 m/s. A stopwatch measures the stone's trajectory time from the top of the cliff to the bottom at 5.6 s. What is the height of the cliff?

A stone is projected at a cliff of height h with an initial speed of 46.0 m/s directed 60.0° above the horizontal. The stone strikes at A, 5.10 s after launching. (a) Find the height, h, of the cliff. ___ m (b) Find the speed of the stone just before impact at A. ____ m/s (c) Find the maximum height H reached above the ground. ____ m

A stone is thrown at an angle of 39 degrees above the horizontal from the top edge of a cliff with an initial speed of 12 m/s. A stopwatch measures the stone's trajectory time from the top of the cliff to the bottom to be 5.6 s. What is the height of the cliff? (Assume air resistance is negligible) a. 197 m b. 58 m c. 154 m d. 111 m

An arrow is shot from a height of 1.5 m toward a cliff of height H . It is shot with a velocity of 30 m/s at an angle of $60^{\circ}$ above the horizontal. It lands on the top edge of the cliff 4.0 s later. (a) What is the height of the cliff? (b) What is the maximum height reached by the arrow along its trajectory? (c) What is the arrow's impact speed just before hitting the cliff?
