Suppose you throw a baseball straight up into the air at t = 0. The ball reaches a maximum height of 22.5 meters above its starting position. Ignore air resistance for this problem. (a) What was the initial velocity of the ball at the moment it left your hand? Hint: the velocity goes to zero at the highest point of the motion. (b) At what time (in seconds) did the ball reach its maximum height? (c) If you threw the ball up into the air with double the initial velocity that you found in part (a), how high would it go?
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.

height of 22.5 meters above its starting position. Ignore air resistance for this problem.
(a) What was the initial velocity of the ball at the moment it left your hand? Hint: the
velocity goes to zero at the highest point of the motion.
(b) At what time (in seconds) did the ball reach its maximum height?
(c) If you threw the ball up into the air with double the initial velocity that you found in
part (a), how high would it go?
According to question we need to find---
- (a) What was the initial velocity of the ball at the moment it left your hand?
- (b) At what time (in seconds) did the ball reach its maximum height?
- (c) If you threw the ball up into the air with double the initial velocity that you found in part (a), how high would it go?
