A rock is thrown vertically upward with a speed of 11.0 m/s from the roof of a building that is 60.0 mabove the ground. Assume free fall. 1) In how many seconds after being thrown does the rock strike the ground? 2)What is the speed of the rock just before it strikes the ground?
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?
Problem 7. A rock is thrown vertically upward with a speed of 19.0 m/s from the roof of a building that is 50.0 m above the ground. Assume free fall. 1. In how many seconds after being thrown does the rock strike the ground? 2. What is the speed of the rock just before it strikes the ground? 3. What is rock's position 2.00 seconds after the throw? 4. What is rock's velocity after its displacement of -20.0m?
A small rock is thrown vertically upward with a speed of 14.0 m/s from the edge of the roof of a 29.0 m tall building. The rock doesn't hit the building on its way back down and lands in the street below. Air resistance can be neglected. Part A What is the speed of the rock just before it hits the street? Express your answer with the appropriate units. HA ? Uy = Value Units Submit Request Answer Part B...
A small rock is thrown vertically upward with a speed of 17.0 m/s from the edge of the roof of a 30.0 m tall building. The rock doesn't hit the building on its way back down and lands in the street below. Air resistance can be neglected. What is the speed of the rock just before it hits the street? How much time elapses from when the rock is thrown until it hits the street?
A small rock is thrown vertically upward with a speed of 23.0 m/s from the edge of the roof of a 39.0-m-tall building. The rock doesn't hit the building on its way back down and lands in the street below. Ignore air resistance. What is the speed of the rock just before it hits the street? How much time elapses from when the rock is thrown until it hits the street?
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...
At t = 0 s, a ball B1 is thrown vertically upward with a speed of 30 m/s. When B1 is 25 m above ground on the way up, a second ball B2 is thrown vertically upward from the ground with a speed of 40 m/s (Take the magnitude of the acceleration due to gravity g =10m/s2) a) How many seconds after B1 was B2 thrown upward?
A rock is thrown vertically upward with a speed of 15 m/s. What are its speed and direction 2 s later? a. 10 m/s upward b. 5 m/s upward c. zero d. 5 m/s downward
A second rock is thrown straight upward with a speed 3.750 m/s. If this rock takes 2.771 s to fall to the ground, from what height H was it released? Express your answer in meters to three significant figures. View Available Hint(s)
