As shown in the figure, a heavy rock is shot upward from the edge of a vertical cliff. It leaves the edge of the cliff with an initial velocity of 15 m/s directed at 25° from the vertical and experiences no appreciable air resistance as it travels. How high is the cliff?
Homework Answers
a acceleration does not change with time. Its value remain - g if we assume downward direction negative and upward direction positive.

00:31:17 A person standing at the edge of a cliff throws a rock upward from a height of 400 ft above ground level with an initial velocity of 62 ft/s. What is the velocity of impact when the rock reaches the bottom of the cliff? Round any intermediate calculations, if needed, to no less than six decimal places, and round your final answer to two decimal places. (Hint: Use h(1) = 1612 + 621 + 400 as the position function,...

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...

A rock is thrown vertically upward from the edge of a cliff. It
leaves your hand at a point even with the edge at a speed of 25
m/s. The rock is then in free fall. On its way back down, it misses
the edge of the cliff and continues its fall towards the river.

your simplified equations using a coordinate system whose y axis is
positive down and the x...

A rock is shot vertically upward from the edge of the top of a tall building.The rock reaches its maximum height above the top of the building 1.80 s after being shot. Then, after barely missing the edge of the building as it falls downward, the rock strikes the ground 10.0 s after it is launched. In SI units: (a) with what upward velocity is the rock shot, (b) what maximum height above the top of the building is reached...
