A ball thrown horizontally with speed vi = 20.0 m/s travels a horizontal distance of d = 58.0 m before hitting the ground. From what height h was the ball thrown?
When setting up projectile motion questions, which of the following characteristics of projectile motion are important to keep in mind?
Check all that apply.
|
a. Projectile motion is the motion of an object that moves in two dimensions under the influence of gravity and air resistance. |
|
b. Although the horizontal and vertical motions of a projectile are independent, they are connected through the time Δt that the object is in the air. |
| c. Projectile motion is made up of two independent motions: uniform motion at constant velocity in the horizontal direction and free-fall motion in the vertical direction. |

To practice Problem-Solving Strategy 3.1 Projectile motion problems. A ball thrown horizontally with speed viviv_i = 20.0 m/sm/s travels a horizontal distance of ddd = 58.0 mm before hitting the ground. From what height hhh was the ball thrown? If it takes a ball dropped from rest 2.900 s to fall to the ground, from what height H was it released? Express your answer in meters.

A ball thrown horizontally at 25 m/s travels a horizontal distance of 50 m before hitting the ground. Part A From what height was the ball thrown? Express your answer in meters. Part B If instead it was launched at an angle of 25 degrees above the horizontal at a velocity of 25 m/s , how high would it go? Express your answer in meters.

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...
