A ball is tossed straight up in the air with an initial velocity of 25 m/s. Answer the questions below assuming g = 10 m/s² downward. Assume an upward positive sign convention. a. What is the velocity of the ball at the top of the toss? b. What is the acceleration of the ball at the top of the toss (include the sign)? c. How long would it take for the ball to reach the top of its toss? d. If the ball were caught at a point 10 m below the height from which it was thrown, what would be its final velocity (just before it was caught).
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.
