A ball is thrown horizontally at a speed of 20. meters per second from the top of a cliff. How long does the ball take to fall 19.6 meters to the ground?
A projectile is launched at an angle of 60.° to the horizontal at an initial speed of 10. meters per second. What is the magnitude of the vertical component of its initial velocity?
The diagram represents a ball being kicked by a foot and rising at an angle of 30.° from the horizontal. The ball has an initial velocity of 5.0 meters per second. [Neglect friction.] As the ball rises, the vertical component of its velocity... decreases, increases, or remins the same
The diagram shows a ball thrown toward the east and upward at an angle of 30° to the horizontal. Point X represents the ball's highest point. What is the direction of the ball's acceleration at point X? [Neglect friction.]
In the diagram, a 10.-kilogram sphere, A, is projected horizontally with a velocity of 30. meters per second due east from a height of 20. meters above level ground. At the same instant, a 20.-kilogram sphere, B , is projected horizontally with a velocity of 10. meters per second due west from a height of 80. meters above level ground. [Neglect air friction.] The magnitude of the horizontal acceleration of sphere A is...
A cannon elevated at an angle of 35° to the horizontal fires a cannonball, which travels the path shown in the diagram. [Neglect air resistance and assume the ball lands at the same height above the ground from which it was launched.] If the ball lands 7.0 102 meters from the cannon 10. seconds after it was fired, what is the vertical component of its initial velocity?
An object is thrown horizontally off a cliff with an initial velocity of 5.0 meters per second. The object strikes the ground 3.0 seconds later. What is the vertical speed of the object as it reaches the ground? [Neglect friction.]
