Sasha stands on the ground and tosses a baseball perfectly vertically up to her friend Helge, who catches it by reaching outside the window of his apartment building. She gives the ball an initial speed of vi= 19.7 m/s, and Helge catches it 1.40 s later when it reaches his hands. If Helge were to drop the baseball from rest at this point, what would be its final speed vf when it reaches Sasha’s hands down below? (She catches the ball at the same height from which she tossed it.)For your limit check, investigate what happens to vf as Sasha’s launch speed gets very large (i.e., as vi→∞). This is my question. I am also trying to figure out what formulas I would use to solve it.
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.
