A rock takes 3.2 s to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.4 m/s. Calculate the height of the cliff (in meters). Using that information, how long would it take to reach the ground if the rock is thrown straight down with the same speed?
A rock is thrown vertically upward with a speed of 15.0 m/s from the roof of a building that is 70.0 m above the ground. Assume free fall. In how many seconds after being thrown does the rock strike the ground? What is the speed of the rock just before it strikes the ground?
A rock is thrown vertically upward with a speed of 14.0 m/s from the roof of a building that is 70.0 m above the ground. Assume free fall. a. In how many seconds after being thrown does the rock strike the ground? b. What is the speed of the rock just before it strikes 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...

A second rock is thrown straight upward with a speed 6.000 m/s, If this rock takes 1.828 s to fall to the ground, from what height H was it released? Express your answer in meters to three significant figures A rock thrown with speed 12.0 m/s and launch angle 30.0 (above the horizontal) travels a horizontal...
A rock takes 2.40 s to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.17 m/s. How long (in s) would it take to reach the ground if it is thrown straight down with the same speed?
A rock is tossed straight up with a speed of 20 m/s. When it returns, it falls into a hole 12 m deep. In other words, assume that the rock lands 12 m lower than the height from which it was thrown. Take "up" to be the positive direction for this problem. Although the numbers in this problem have less than 3 significant figures, please enter your answers with at least 3 significant figures, and remember that velocity is a...
