 * 1) 6. When a football player throws a football, he is exerting a force on the football, causing it to move in a horizontal direction. However, gravity is also exerting a force on the football, causing it to move vertically. The displacement of the football can be separated into horizontal and vertical vectors.
 * 2) 7. An archaeologist climbs the Great Pyramid in Giza, Egypt. The pyramid's height is 136 m and its width is 2.30 X 10^2. What is the magnitude and the direction of the displacement of the archaeologist after she has climbed from the bottom of the pyramid to the top?

While if the curve is more shallow, the acceleration is slower. 7. || 4. 5.Links [|http://en.wikipedia.org/wiki/Newton's_laws_of_motion] [] [] [] [] 6. A man exerts a force on a large block. The inertia of the block resists movement until a certain amount of force is exerted upon it. At which point, it will require another force in the opposite direction to stop the block from moving. 7.Roberto and Laura are studying across from each other at a wide table. Laura slides a 2.2kg book toward Roberto. If the net force acting on the book is 1.6N to the right, what is the book's acceleration? || 4. 5.Links [] [] [] 6. A rock rolls off of a cliff. Gravity is pushing the rock down, causing it to accelerate at a constant rate. However, wind resistance is also acting on the rock, causing its acceleration to be slower than the given force of gravity. 7. || 4. 5.Links [] []

6. A baseball is thrown from the top of a building. Its starting velocity is in a horizontal direction. However, gravity adds a vertical acceleration to the baseball, causing it to fall at an accelerating velocity while keeping its horizontal motion. 7. || 4.  5.Links [] [] [] [] 6. 7. || 4. 5.Links [] [] [] []

6. The static friction of a large block keeps the block from going into motion when a force is exerted upon it. However, once the block starts moving, the kinetic friction acts to stop the motion. 7. || 4.  5.Links [] [] [] [] 6. 7. || 4. 5.Links [] [] [] 6. 7. || P-2.1 Equations Velocity=meters / seconds Force = Mass x Acceleration Cx = Ax + Bx
