559 m 5. A student standing on the building at height 50.0 meter, shooting a yellow ball with velocity 20 m/s up, another student standing with him together, at same time, shooting a blue ball with velocity -20 m/s down. When does the yellow ball hit the ground? When does the blue ball hit the ground? What is yellow ball touch down velocity? What is blue ball touch down velocity?
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 student is standing on a hill that is 3.5 m high above level ground. a wall that is on level ground is 15 m away from the student. the student decudes to throw a ball horizontally at a combined height of 4.5 m at the wall. the student measures the time it takes to make an impact and finds it to be .64 s. at what height did the student hit the side of the wall.
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 23.0° 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 (b) Find the height from which the ball was thrown. m (c) How long does it take the ball to reach a point 10.0 m below the...

(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...
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...
A ball is lossed from an upper-story window of a building. The ball is given an initial velocity of 7.60 m's at an arngle of 24.0° below the horizontal. Il strikes the grournd 5.00 s later (a) How far horizontally from the base of the building does the ball strike the ground? (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 below the level of...
A cannon fires a ball horizontally with a velocity of 240 m/s. If the cannon is in a 44 meter tall tower and the ground below is flat, then (a) How long does the ball take to hit the ground after being fired? (b) At what horizontal distance from the cannon does the ball hit the ground? and (c) What are the horizontal and vertical components of the ball's velocity just before it hits the ground?
A baseball is thrown from the roof of a 30.0-m-tall building with an initial velocity of magnitude 17.0 m/s and directed at an angle of 53.1° above the horizontal. (a) What is the speed of the ball just before it strikes the ground? Use energy methods and ignore air resistance. m/s (b) What is the answer for part (a) if the initial velocity is at an angle 53.1° below the horizontal? m/s
1. A student standing on the edge of a cliff throws a rock downward at a speed of 7.5 m/s at an angle 40° below the horizontal. It takes the rock 2.4 seconds to hit the ground. How far from the base of the cliff will the rock land? a)18 m b)5.7 m c)13.8 m d)11.6 m 2. A person driving through a field has velocity components that are 30 m/s west and 20 m/s south. What is the magnitude...
