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.

A stone is thrown horizontally from the highest point of a 95 m building and lands 115 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the highest point of the building, with positive y upwards and positive x in the direction of the throw. How long is the stone in the air in seconds? What must have been the initial horizontal component of the velocity, in meters per second? What is the vertical component of the velocity just before the stone hits the ground, in meters per second? What is the magnitude of the velocity of the stone just before it hits the ground, in meters per second?
A golfer is attempting to reach the elevated green by hitting his ball under a low-hanging branch in one tree A, but over the top of a second tree B. If the launch speed of the golf ball is v0 = 112 mi /hr, what launch angle θ will put the first impact point of the ball closest to the pin? How far from the pin (distance d) is this impact point?
Eddie Manalak is a Filipino stuntman, he wishes to cross the 520m distance between two tall buildings by being shot from a cannon. He wishes to be launched at 60° to the horizontal so that he can spend more time in waving to the crowd. With what speed must he be launched? ANS. 76.7 m/s
A regulation volleyball court measures L = 18.0 meters in length and d = 2.43 meters in height. A volleyball player hits the ball from a height of h = 1.50 m just over the backline, and the initial velocity of the ball creates an angle of q = 30° with the ground. At what initial speed must the ball be struck such that it barely clears the net?
A pilot flies horizontally at 1300 km/h, at height h = 35 m above initially level ground. However, at time t = 0, the pilot begins to fly over ground sloping upward at angle u = 4.3°. If the pilot does not change the airplane’s heading, at what time t does the plane strike the ground?
Two kittens are running toward each other, one is named Chloe and the other is named Luna. Luna runs at a speed of 1.90 m/s. If Chloe jumps at an angle of 14.0° with speed 2.80 m/s, at what distance from Luna should Chloe jump to make sure she lands on Luna?
In the figure, a ball is launched with a velocity of magnitude 7.00 m/s, at an angle of 41.0° to the horizontal. The launch point is at the base of a ramp of horizontal length d1 = 6.00 m and height d2 = 3.60 m. A plateau is located at the top of the ramp. Does the ball land on the ramp or the plateau? When it lands, what are the magnitude and angle of its displacement from the launch point?
In the horizontal shooting test, if the height of the ball ejected from the assembly is y = 0.25m and the distance it travels in the horizontal is x = 0.65m, what is the launch speed (m / s) of the ball?
In the figure, a ball is launched with a velocity of magnitude 6.00 m/s, at an angle of 44.0° to the horizontal. The launch point is at the base of a ramp of horizontal length d1 = 6.00 m and height d2 = 3.60 m. A plateau is located at the top of the ramp. (a) Does the ball land on the ramp or the plateau? When it lands, what are the (b) magnitude and (c) angle of its displacement from the launch point?
A projectile is launched from ground level at an angle θ to the top of a cliff which is 195 m away and 155 m high. If the projectile lands right on the cliff edge 7.6 s after it is fired, find the initial velocity of the projectile.
A Chinook salmon can jump out of water with a speed of 7.30 m/s . How far horizontally ? can a Chinook salmon travel through the air if it leaves the water with an initial angle of ?=30.0° with respect to the horizontal? (Let the horizontal direction the fish travels be in the +? direction, and let the upward vertical direction be the +? direction. Neglect any effects due to air resistance.)
A ball is tossed horizontally from the highest point of a 75 m building and lands 150 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the highest point of the building, with positive y upwards and positive x in the direction of the throw. What must have been the initial horizontal component of the velocity, in meters per second?
