A stone is thrown vertically into the air at a velocity of 60 m/sec. After 4 seconds, another stone is thrown vertically into the air. a. Determine the time that the first ball has travelled in order to meet the second ball 120 m from the ground. Ans. t1 = 6.1 sec , t2 = 3.6 sec b. Determine the time that the second ball has travelled in order to meet the first ball 120 m from the ground. Ans. t3 = 5.7 sec c. What initial velocity must the second ball have in order to meet the first ball 120 m from the ground? Ans. V3 = 49 m/sec Please indicate the formula and what to find given value.
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.
