A ball is thrown upward with an initial velocity of 14 m/s. Using the approximate value of g = 10 m/s^2, what are the magnitude and direction of the ball’s velocity a. 1 second after it is thrown? b. 2 seconds after it is thrown?
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.
E7. A ball is thrown upward with an initial velocity of 14 m/s. Using the approximate value of g = 10 m/s^2, what are the magnitude and direction of the ball’s velocity a. 1 second after it is thrown? b. 2 seconds after it is thrown?
E8. How high above the ground is the ball in exercise 7
a. 1 second after it is thrown? b. 2 seconds after it is thrown?
only need question 8, the rest is for reference
