From the top of a 20 m tall building (its a two story building) you throw a rock, releasing it at a height level with the top of the building and with the rock going 6.0 m/s at 30 ° below the horizon- tal. What is the y-component of the velocity of the rock when it reaches a speed of 12 m/s, and how high above the ground is it at that instant? Answer is -11m/s and 14 m, but...

A rock is thrown with an initial speed v0 from the top of a building at an angle θ (theta) above the horizontal. It hits the ground below after traveling a horizontal distance L. Find an expression for the height of the building. Your answer should be in terms of v0, L, θ (theta), and g, as needed. Please show all work!

A mischievous SUOC student has climbed on the roof of a snow-covered building and is trying to hit her friend with snowballs as he walks through the Quad. She throws them at an angle of 20◦ above the horizontal at a speed of v0 = 5 m/s. The building has a height h = 6 m. He decides to throw a snowball back at her. He’s standing a distance d from the side of the building, and throws a snowball...

You are on the roof of a tall building. Your TA (who is 1.8m tall) is walking by, and you drop (from rest at the level of the roof) a water balloon on him. It takes 2s for the balloon to go from the roof of the building to your TA's head. (a) How tall is the building? (b) What was the velocity of the balloon when it hit your TA? If instead of dropping the balloon from rest, you...

Standing on the roof of a 61 m tall building, you throw a ball straight up with an initial speed of 19.5 m/s. If the ball misses the building on the way down, how long will it take from you threw the ball until it lands on the ground below? Give your answer in seconds and round the answer to three significant figures.

You throw a 0.5 kg rock upward from your hand (which is 1 m off the ground when the rock leaves it). The rock rises to a maximum height of 2.5 m and then falls past your hand to the ground. From the moment you let it go until the moment just before it lands, what can you say about the work that gravity does on the rock? Group of answer choices a. Gravity does negative net work on the...

You throw a rock with an initial horizontal velocity and it hits the ground at x meters away from your feet. What if: (a) You throw the same stone with the same initial conditions but instead you do this on a another planet with a mass 4 times the mass of the earth. With what factor will x change? (b) You throw the same stone with the same initial conditions but instead you do this on a another planet with...
