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...
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...
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 2.45 kg rock is dropped from the top of a 15.5m vertical cliff a)What is the potential energy of the rock relative to the base of the cliff before it is dropped b) What is the kinetic energy of the rock just before it hits the ground below? c) What is the velocity of the rock at a point 5.00 m above the base of the cliff? d) How much total energy does the rock have half way down?
A rock is dropped from the top of a vertical cliff and takes 3.00 s to reach the ground below the cliff. A secon rock is thrown vertically from the cliff, and it takes this rock 2.00 s to reach the ground below the cliff from the time it is released. With what velocity was the second rock thrown, assuming no air resistance? Select one: a. 5.51 m/s downward , b. 4.76 m/s downward X O c. 12.3 m/s downward...
If you drop a rock vertically off a cliff that is 56.2m high, how long will it take for the rock to hit the ground?
A 0.26-kg rock is thrown vertically upward from the top of a cliff that is 32 m high. When it hits the ground at the base of the cliff, the rock has a speed of 33 m/s . Part A Assuming that air resistance can be ignored, find the initial speed of the rock.(Express your answer using two significant figures.) Part B Find the greatest height of the rock as measured from the base of the cliff. (Express your answer...
7. A baseball is thrown horizontally off a cliff at 23 m/s. The cliff is 50 m high. Ignore air drag. A.) How LONG will it take the baseball to hit the ground?B.) How FAR from the base of the cliff will the baseball hit the ground? C.) Upon impact, how FAST was the baseball going? D.) At what ANGLE (relative to the horizontal) did the baseball impact the ground?
The Heigth of a cliff relative to the ocean below is 57 m. Someone kicks a rock horizontally off of the cliff and hears the sound 4.62s later. a. How long does it take for the rock to hit the water? b. How far must the sound travel to get back to the cliff? assume that sound moves in a straight line with a speed of 343 m/s. c. Relative to the base of the cliff, where does the rock...
A child standing on the edge of a sheer cliff wall throws a rock down towards the ground below. The rock is thrown 27° below the horizontal at a speed of 14m/s & lands 13 m from the base of the cliff wall. Ignore air drag. A.) Determine how long the rock was in the air. B.) Determine how high the cliff wall is. C.) Determine how fast the rock was going upon impact. D.) Determine the angle of impact....
