If a ball is released from a window ledge, how fast will it be travelling when...
A man is standing on a ledge when he throws a ball. The speed of the ball when released from his hand is 20.0 m/s . The ball is 45.0 m above the ground when released from the man's hand. On the ground below, a boy begins running away from a point directly below the man on the ledge at a constant speed of 6.00 m/s. The boy runs in a straight line along the ground. As the boy runs,...
From the window of a building, a ball is tossed from a height y0 above the ground with an initial velocity of 8.30 m/s and angle of 18.0° below the horizontal. It strikes the ground 4.00 s later. (a) If the base of the building is taken to be the origin of the coordinates, with upward the positive y-direction, what are the initial coordinates of the ball? (Use the following as necessary: y0. Assume SI units. Do not substitute numerical...
A boy reaches out of a window and tosses a ball straight up with aspeed of 10 m/s. The ball is 20 m above the ground as he releasesit. Use energy to find a.The ball's maximum height above the ground. b.The ball's speed as it passes the window on its waydown. c.The speed of impact on the ground.
A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.45 m/s at an angle of 21.9o below the horizontal. It strikes the ground 3.00 s later. How far horizontally from the base of the building does the ball strike the ground? Calculate the height from which the ball was thrown. How long does it take the ball to reach a point 12.0 m below the level of launching?
A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 7.70 m/s at an angle of 25.0 degree below the horizontal. It strikes the ground 3.00 s later. (a) How far horizontally from the base of the building does the ball strike the ground? 19.98 (b) Find the height from which the ball was thrown. 56.55 m (c) How long does it take the ball to reach a point 10.0 m...
rom the window of a building, a ball is tossed from a height y0 above the ground with an initial velocity of 9.50 m/s and angle of 16.0° below the horizontal. It strikes the ground 6.00 s later. (a) If the base of the building is taken to be the origin of the coordinates, with upward the positive y-direction, what are the initial coordinates of the ball? (Use the following as necessary: y0. Assume SI units. Do not substitute numerical...
A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 9.30 m/s at an angle of 21.0° below the horizontal. It strikes the ground 6.00 s later. (a) How far horizontally from the base of the building does the ball strike the ground? m Enter a number. (b) Find the height from which the ball was thrown. (c) How long does it take the ball to reach a point 10.0 m...
You throw a ball from your window 14 meters above the ground. When the ball leaves your hand, it is moving at a speed of 20 m/s at an angle of 10 degree below the horizontal. Choosing a coordinate system such that its origin is located on your hand, the positive x axis is down and the positive y axis is right. Calculate how far horizontally from your hand, the ball lands.
A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 7.90 m/s at an angle of 23.0° below the horizontal. It strikes the ground 5.00 s later. (a) How far horizontally from the base of the building does the ball strike the ground? 1 m (b) Find the height from which the ball was thrown. 2 Your response differs from the correct answer by more than 10%. Double check your calculations....
