The position of a particle is given by $x ( t ) = 23 t - 1.2 t ^ { 3 }$ , where x(t) is in meters and t is in seconds. The initial ( $t = 0$ E) position of the particle
A) is 0 m.
B) is 2.3 m.
C) is 23 m.
D) cannot be determined.

Question

Quizplus · Accepted Answer

The initial position of the particle is found by substituting $t = 0$ into the equation $x(t) = 23t - 1.2t^3$, which gives $x(0) = 23(0) - 1.2(0)^3 = 0$.

The Position of a Particle Is Given By x(t)=23t−1.2t3x ( t ) = 23 t - 1.2 t ^ { 3 }x(t)=23t−1.2t3
