A 3.00N rock is thrown vertically into the air from the ground. At h-15.0m, V-25m/s upward. Use the work-energy theorem to find the initial speed of the rock. 3's 30.3s None of the ahove It takes 12.0J to stretch a spring 3.00cm What is the force necessary to do this? None of the ahove
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?
Question S A ball is thrown from a height of horizontal. Assume air resistance is negligible. 20 meters with an initial velocity of 10 m/s at an angle of 30 above the an initial (a) Find the x and y components of the ball's initial velocity (b) What is the maximum height in meters reached by the ball? (c) For how many seconds is the ball in the air? (d) What is the total distance from the launch point to...
Q3 Part 1 (a) With what speed must a ball be thrown vertically from ground level to rise to a maximum height of 50 m? (b) How long will it be in the air? [2+3] Part 2 A particle's acceleration along an x axis is a = 5t, with t in seconds and a in meters per second squared. At t = 2 s, its velocity is 17 m/s. What is its velocity at t = 4 s? [3]
A rock is at a height of 21.9 m above the ground and is thrown at 12.2 degrees below the horizontal. It hits the ground 49.5m horizontal from where it was thrown. A) what is the initial velocity of the rock? B) what is the final velocity of the rock?
Question 6 Flag question Marked out of 12.00 Not yet answered A rock is thrown with an initial velocity of 30 m/s at an angle of 60 above the horizontal from a height of 1.5 m toward a cliff. After 4 seconds, the rock lands on the top edge of the cliff. (a) Calculate the height of the cliff, (b) Calculate the maximum height reached by the rock along its trajectory (c) Determine the speed of the rock just before...
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 rock is thrown horizontally from the top of a building with a velocity 12.2m/s the rock lands on the ground 103.0m from the edge of the building what is the height of the building? what is the rock's velocity just before hitting the ground?
