From the top of a cliff, a person throws two stones. The cliff is 20.9 m high. The two stones have idential intial speed of 19.8 m/s and are both thrown at an angle of 36.3, one stone was thrown below the horizontal and one above the horizontal. What is the distance between the points where the stones strike the water? Neglect air resistance.

At t=0, a projectile is launched from ground level with an initial speed of vi. at t=1.5s, it is displaced d=33 m horizontally from the launch point and h=25m above the launch point. let +x be to the right and +y upward. Ignore air resistance. a) what is the x component of v0x of the projectiles velocity immediately after it is launched? b) what is the y component voy of the projectile's velocity after it is launched? c) what is the maximum height reached above the ground?

Parts needed: D-F. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of  v0 = 15.0 m/s.  The cliff is h = 36.0 m above a flat, horizontal beach. (a) What are the coordinates of the initial position of the stone? x0: y0:  (b) What are the components of the initial velocity? v0x: v0y:  (c) Write the equations for the x- and y-components of the velocity of the stone with time. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not include units in your answer.) vx: vy:  (d) Write the equations for the position of the stone with time, using the coordinates in the figure. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not state units in your answer.) x= y= (e) How long after being released does the stone strike the beach below the cliff? (f) With what speed and angle of impact does the stone land? vf= 0-: (theta):

A rock is thrown off a clift at an angle of 24.5 degrees above the horizontal. The clift in 168.9 m high. The inital speed of the rock is 16.7 m/s. what is the range of the rock?
