The Position of an Object Subjected to Constant Acceleration Can

Multiple Choice

The position of an object subjected to constant acceleration can be described by the following $$\begin{array} { l } \text { function: } \quad x ( t ) = x _ { 0 } + v _ { 0 } t + \frac { 1 } { 2 } a t ^ { 2 } \\\text { where } x = \text { position } ( \mathrm { m } ) \\x _ { 0 } = \text { initial position } ( \mathrm { m } ) \\v _ { 0 } = \text { initial velocity } ( \mathrm { m } / \mathrm { s } ) \\a = \text { acceleration } \left( \mathrm { m } / \mathrm { s } ^ { \wedge } 2 \right) \\t = \text { time } ( \mathrm { sec } ) \end{array}$$ Which type of mathematical model is used here to describe the object's position?

A) Linear model
B) Nonlinear model
C) Exponential model
D) Trigonometric model
