There is a massive particle, whose position across time is described by the function vec$(r)(t)=$vec$(a)$ where vec$(a)$ is a constant vector. Which of the following statement about this particle must be false? Select all that applies.

Note that

vec$(p)=m\frac{d(vec(r))}{dt}$

$T=\frac{\text{v}\text{e}\text{c}(p{)}^2}{2m}$

Let $t_1,t_2$ be any two distinct time values.

$V(t)=0$

$m(t_1)($meaning mass at time $($:$t_1\}$

vec$(p)(t_1)=$vec$(p)(t_2)$

$m>0$

$E(t)=0$

vec$(r)(t_1)$vec$(r)(t_2)$

$T>0$

$\frac{d(vec(r))}{dt}(t_1),$ which means $\frac{d(vec(r))}{dt}$ at $t_1,$ is equal to $\frac{d(vec(r))}{dt}(t_2)$
