A ball is thrown horizontally from the top of a 69.0-m building and lands 105.8 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the +x direction and upward to be in the +y direction.)
How long (in s) is the ball in the air?
What must have been the initial horizontal component of the velocity (in m/s)? (Indicate the direction with the sign of your answer.)
What is the vertical component of the velocity (in m/s) just before the ball hits the ground? (Indicate the direction with the sign of your answer.)

A ball is thrown horizontally from the top of a 60.0-m building and lands 110.0 m from the base of the building. Ignore air resistance. (a) How long is the ball in the air? (b) What must have been the initial horizontal component of the velocity? (c) What is the vertical component of the velocity just before the ball hits the ground? (d) What is the velocity (including both the horizontal and vertical components) of the ball just before it...
A ball is thrown horizontally from the top of a 95 m building and lands 110 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the top of the building, with positive y upwards and positive x in the direction of the throw. Part (a) How long is the ball in the air in seconds? Part (b) what must have been the initial horizontal component of the velocity, in meters per second? Part(c)...
A ball is thrown horizontally from the top of a 57 m vertical cliff and lands 92 m from the base of the cliff. What is the vertical component of the velocity of the ball just before it hits the ground?
A ball is thrown horizontally with an initial speed of 30m/s from the top of a building 45m tall. a. How far away from the building will the ball hit the ground? b. What is the horizontal component of its velocity when it hits the ground? c. Find the magnitude and direction of the velocity when it hits the ground?
A ball is thrown horizontally from the top of a 25 m vertical cliff and lands 101 m from the base of the cliff? what is the speed of the ball just before it hits the ground?
Back on Earth, a ball is thrown off a roof top with a horizontal velocity 7.4 m/s and a upward vertical velocity 3.9 m/s. It hits the ground 3.8 s later. What is the direction at which the ball hits the ground? Give the angle the velocity vector makes with vertical (straight down = 0o and horizontal = 90o). Use g = 9.8 m/s2 if needed and neglect air friction. Read carefully -- there are versions of this question with...
PROBLEM: A ball is thrown downward from the top of a building at an angle of 30.0° below the horizontal. The point of release is 49.0 m above the ground and the ball lands 67.7 m from the base of the building. (a) How long does it take for the ball to hit the ground? (b) Find the ball's initial speed. (c) the speed and angle of the velocity vector with respect to the horizontal at impact. Neglect air resistance.
