A ball is thrown vertically with velocity vi from a height of h = 50 m and lands on the ground after a time interval Δt. The positive y-direction is upward. Refer to the figure. 1 - What is the value of the vertical component of acceleration of the free fall motion in meters per second squared? 2 - Enter an expression for the vertical component of the total displacement of the motion, Δy, in terms of initial height h.
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
A ball is thrown vertically with velocity vi from a height of h = 50 m and lands on the ground after a time interval Δt. The positive y-direction is upward. Refer to the figure.
1 - What is the value of the vertical component of acceleration of the free fall motion in meters per second squared?
2 - Enter an expression for the vertical component of the total displacement of the motion, Δy, in terms of initial height h.
3 - Enter an expression for Δy in terms of Δt, a, and the vertical component of the initial velocity of the motion, vi.
4 - If the ball starts from rest, what is vi, in meters per second?
5 - Enter an expression for Δt in terms of a and Δy, in the case when the ball starts from rest.
6 - Calculate the fall time Δt, in seconds, when the ball starts from rest.
6 - Returning now to the general case, vi ≠ 0, enter an expression for the vertical component of the final velocity, vf, right before the ball hits the ground, in terms of vi, a, and Δt.
7 - Calculate the value of vf in meters per second when the ball starts from rest
