A rock is thrown downward at an angle of -25 degrees (with respect to horizontal) off of a 35 m high cliff at a speed of 10 m/s. How far from the base of the cliff will the rock land? (The solution is 20.6 m, but I am not sure how to arrive at this answer.)

A rock is thrown off a cliff at an angle of 51° above the horizontal. The cliff is 130 m high. The initial speed of the rock is 20 m/s. (Assume the height of the thrower is negligible.) (a) How high above the edge of the cliff does the rock rise (in m)? (b) How far has it moved horizontally when it is at maximum altitude (in m)? (c) How long after the release does it hit the ground (in s)? (d) What is...
Consider a rock thrown off a bridge of height 79.8 m at an angle theta = 25 degree with respect to the horizontal as shown in Figure P4.20. The initial speed of the rock is 10.5 m/s. Find the following quantities: the maximum height reached by the rock the time it takes the rock to reach its maximum height the time at which the rock lands how far horizontally from the bridge the rock lands the velocity of the rock...
A rock is thrown off a cliff at a velocity of 15m/s and at an angle of 35 degrees. It lands 200 meters away. What was the height of the cliff? What was the velocity right before it landed?
A man throws a rock off the edge of a cliff at a 30° angle and initial total velocity of 10 m / s. When the rock leaves his hand, it is 35 meters above the ground. How far from the edge of the cliff will the rock land?
A rock Is thrown horizontally with a speed of 17 m/s from a vertical cliff of helght 31 m (a) How long does it take to reach the horizontal ground below? 2.515 (b) How far wll It land from the base of the cllff? 42.759 (c) What is the velocity (magnitude and direction counterclockwise from the +x-axis, which is the initial horizontal direction in which the rock was thrown) of the rock just before it hits the ground? Magnitude 29...
1. A rock is thrown horizontally off a cliff. I the cliff has a height h, and the rock has an impact angle θ with the surface of the water at the base of the cliff (see diagram), find an expressionin terms of some or all of 0, h, and g) for the initial speed with which the rock is thrown. [8 pts
You throw a baseball at an angle of 60 degrees with respect to the horizontal with a speed of 20 m/s as it leaves your hand. a. Making reasonable simplifying assumptions, how far from you is the ball when it lands. b. It is possible to throw a second baseball from the same location and with the same initial speed (20 m/s) but at an angle of 30 degrees with respect to the horizon, and this second ball can land...
Two identical rocks are thrown off a cliff. The first rock is thrown horizontally with speed . The second rock is thrown downward, 30˚ below the horizontal, with a speed equal to . Which hits the ground first? (multiple choice A. Not enough information is given to answer the question. B. The first rock hits first. C. They hit at the same time. D. The second rock hits first.
1. A rock is thrown horizontally off a cliff. If the cliff has a height h, and the rock has an impact angle θ with the surface of the water at the base of the cliff (see diagram), find an expression (in terms of some or all of, h, and g) for the initial speed with which the rock is thrown. [8 pts
4. A rock is thrown at an angle of 30 degrees above the horizontal and takes a time “T” before reaching its maximum height. a. Draw the picture, insert coordinate system and list the parameters between the initial point and the point at maximum height. Given [T] Determine: b. The initial speed of the rock. c. The horizontal distance the rock travels to reach its maximum height. d. The maximum height the rock attains. e. The speed of the rock...
