You are on the roof of a tall building. Your TA (who is 1.8m tall) is...
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.
A 3.00 kg ball is dropped from the roof of a building 176.4 m high. While the ball is falling to Earth, a horizontal wind exerts a constant force of 12.0 N on it. a.)How far from the building does the ball hit the ground? b.)How long does it take to hit the ground? c.)What is its speed when it hits the ground?
A stone is dropped from the roof of a building; 1.90 s after that, a second stone is thrown straight down with an initial speed of 27.0 m/s , and the two stones land at the same time. A) How long did it take the first stone to reach the ground? B) How high is the building? c) What are the speeds of the two stones just before they hit the ground? Enter your answers numerically separated by a comma.

You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 350 from the edge of the building with an initial velocity of 13 m/s and lands 57 meters away from the wall. How tall, in meters, is the building that the child is standing on?
A large building has an inclined roof. The length of the roof is 45.5 m and the angle of the roof is 20.0° below horizontal. A worker on the roof lets go of a hammer from the peak of the roof. Starting from rest, it slides down the entire length of the roof with a constant acceleration of 3.35 m/s2. After leaving the edge of the roof, it falls a vertical distance of 28.0 m before hitting the ground. (a)...
A large building has an inclined roof. The length of the roof is 45.5 m and the angle of the roof is 23.0° below horizontal. A worker on the roof lets go of a hammer from the peak of the roof. Starting from rest, it slides down the entire length of the roof with a constant acceleration of 3.83 m/s2. After leaving the edge of the roof, it falls a vertical distance of 30.5 m before hitting the ground. (a)...
You throw a stone vertically upward from the roof of an 80 m tall building with a velocity of 50 m/s. At what velocity, the stone will hit the ground? [Assume g=10m/s2] (ROUND ALL CALCULATIONS TO THE FOURTH DECIMAL PLACE)
A rock is thrown down with an initial speed of 15.0 m/s from the roof of a building to the street below. It takes 3.30 s for the rock to hit the street. (a) Find the speed of the rock as it hits the street. (b) How tall is the building?
