A ball is thrown straight up from the edge of the roof of a building. A second ball is dropped from the roof a time of 1.14 s later. You may ignore air resistance. Part A If the height of the building is 21.0 m, what must the initial speed be of the first ball if both are to hit the ground at the same time? m/s Submit Request Answer Incorrect; Try Again; 3 attempts remaining Part B Consider the...
A ball is thrown straight up from the edge of the roof of a building of height 60.0m. A second ball is dropped from the roof 2s later. What must be the initial speed of the first ball if both are to hit the ground at the same time?
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 roof tile falls from rest from the top of a building. An observer inside the building notices that it takes 0.17 s for the tile to pass her window, which has a height of 1.26 m. How far above the top of this window is the roof?
A roof tile falls from rest from the top of a building. An observer inside the building notices that it takes 0.29 s for the tile to pass her window, which has a height of 1.3 m. How far above the top of this window is the roof?
A ball is thrown from the top of a building with an initial velocity of 23.7 m/s straight upward, at an initial height of 52.0 m above the ground. The ball just misses the edge of the roof on its way down, as shown in the figure. (a) Determine the time needed for the ball to reach its maximum height. s (b) Determine the maximum height. m (c) Determine the time needed for the ball to return to the height...
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)...
A ball is released from a tower at a height of 100 meters toward the roof of another tower that is 25 meters high. The horizontal distance between the two towers is 20 meters. With what horizontal velocity should the ball be imparted so that it lands on the rooftop of the second building?
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 ball with mass 0.15 kg is thrown upward with initial velocity 20 m/sec from the roof of a building 30 m high. there is a force due to air resistance of |v|/30, where velocity v is measured in m/sec.a. find the maximum height above the ground the ball reaches.b. find the time the ball hits the ground.you cannot use the kinematic equations.
