During an ice show a 40.0 kg skater leaps into the air and is caught by an initially stationary 85.0 kg skater. (a) What is their final velocity in meters per second assuming negligible friction and that the 40.0 kg skater's original horizontal velocity was 4.00 m/s? (Enter a number.) m/s (b) How much kinetic energy is lost in joules? (Enter a number.)
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.
