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?
an object having a mass of 150 kg is dropped from the top of a
cliff that is 100 m high. find its potential and kinetic energy
after it has fallen 25 meters.
JAn object having a mass of 1 kg is dropped from the top of that is 100m high. Find its potential and kinetic energy after it has fallen 25 meters
A rock dropped from a cliff falls one-fourth of its total distance to the ground in the last second of its fall. Determine the height of the cliff. (10 pts)
7 A ball has a mass of 0.5 kg. Dropped from a cliff top, the all strikes the sea below at a velocity of 10 m/s. /s. a) What is the kinetic energy of the ball as it is about to b) What was its potential energy before it was c) From what height was the ball dropped? strike the sea? dropped? Repeat stages a, b, and c above to find the height t is a d) A stone of...
A rock is dropped off the edge of a cliff and its distance s (in feet) from the top of the cliff after t seconds is s(t) = 16t. Assume the distance from the top of the cliff to the water below is 400 ft. Answer part (a) and (b). (a) When will the rock strike the water? The rock will strike the water at 5 seconds. (Type an integer or a simplified fraction.) (b) Make a table of average...
A rock is dropped from a sea cliff and the sound of it striking the ocean is heard 3.6s later. If the speed of sound is 340 m/s, how high is the cliff?
A rock is dropped from a sea cliff, and the sound of it striking the ocean is heard 3.0 seconds later. If the speed of sound is 340 m/s, how high is the cliff?
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...
