6. A mass attached to a spring moves horizontally on a smooth surface. The position of the spring (in cm) in terms of the time (in sec) is given by s(t) = 8 sin(t). a) Find expressions for the velocity and for the acceleration of the mass at time t TL b) What are the position, velocity, and acceleration of the mass at t = sec. and at t = лsес? Is the mass moving forward or backward? Is it going faster or slowing down? bns voolav 4 c) When does the mass stop? 8 cm √2 s √2 b) v(t) = 8 cos(t), a(t) = -8 sin(t): c) s() = cm, v()= a()= moving forward, slowing down and S(7) = 0. v(n) = -8 a(n) = Omoving backward and constant velocity; d) t = 2 sec (approximately 1.5 sec, 4.7 sec, 7.8 sec, ...) л Зл 8 cm
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.
