- 4.) A ball thrown horizontally at 22.2 ms from the roof of a building lands 36.0 m from the base of the building. How tall is the building? Choose downward to be the positive y direction. The origin is the point where the ball is thrown from the roof of the building. In the vertical direction, 0 0 y v 0, 0 y, and 9.80m s2 y a. The initial
- Apr 03, 2010 · let's say you're standing on top of a cliff, and you throw a ball horizontally at a certain velocity. When trying to find the time it takes for the ball to reach the ground, why don't you take the initial velocity into account? Wouldn't a ball thrown at 100 m/s take longer to reach the ground, than a ball thrown at 5 m/s? But in the equation to figure out the time, we only take into account ...
- Projectile Motion Example. Let's say you're on top of a cliff, which drops vertically 150 m to the ocean below. You throw a ball with an initial speed of 8.40 m/s at an angle of 20 degrees above the horizontal.
- 6. A ball is thrown horizontally at a speed of 24 meters per second from the top of a cliff. If the ball hits the ground 4.0 seconds later, approximately how high is the cliff? (a) 6.0 m (b) 78 m (c) 39 m (d) 96 m 7. A golf ball is propelled with an initial velocity of 60 meters per second at 37° above the horizontal.
- A ball is thrown horizontally at a speed of 24 meters per second from the top of a cliff. If the ball hits the ground 4.0 seconds later, approximately how high is the cliff? 80m A monkey throws a banana horizontally from the top of a tree.
- A ball is kicked horizontally at 8.0 m/s from a cliff 80m high. How far from the base of the cliff will the stone strike the ground? 2. How long will it take a shell fired from a cliff at an initial velocity of 800 m/s at an angle 30° below the horizontal to reach the ground 150m below? 3.
- Determine the launch speed of a horizontally launched projectile that lands 26.3 meters from the base of a 19.3-meter high cliff. 14. A soccer ball is kicked horizontally at 15.8 m/s off the top of a field house and lands 33.9 metes from the base of the field house. Determine the height of the field house.
- Answers: 2 on a question: A cannonball is fired horizontally from the top of a cliff. The cannon is at height H = 70.0 m above ground level, and the ball is fired with initial horizontal speed v0. Assume acceleration due to gravity to be g = 9.80 m/s2. Given that the projectile lands at a distance D = 150 m from the cliff, find the initial speed of the projectile, v0. Express the initial speed ...
