The position x of a particle at time t
WebbThe displacement of a particle moving in a straight line is a vector defined as the change in its position. If the particle moves from the position x ( t 1) to the position x ( t 2), its displacement is x ( t 2) − x ( t 1) for the time interval [ t 1, t 2]. The distance travelled by a particle is the 'actual distance' travelled. Webbv ( t) = s ′ ( t) = 3 t 2 − 12 t + 9 = 3 ( t − 1) ( t − 3). The particle is moving to the right when the velocity is positive, and to the left when the velocity is negative. Looking at 3 ( t − 1) ( …

WebbThe position of a particle is defined by s(t) = 4t 3 – 3t 2 + 2t. At what time (to the nearest hundreth) is its velocity equal to 384? Start by finding the velocity function: v(t) = s'(t) = 12t 2 – 6t + 2. To find the time, set v(t) equal to 384: 384 = 12t 2 – 6t + 2. To solve, set equal the equation equal to 0: 12t 2 – 6t – 382 = 0 WebbEquation Of Position Of Particles as a Function of Time The key notions used to describe the motion of objects are: t: the time, measured in seconds [s].
