A particle moves along a line such that its position is given by the equation p ( t ) = 50 t t + 2 p(t)=\frac{50t}{t+2} , where p p is the position in meters from the origin and t t is the time in seconds. Calculate the particle's velocity function.

100 ( t + 2 ) 2 \frac{100}{\left(t+2\right)^2}

− 100 ( t + 2 ) 2 -\frac{100}{\left(t+2\right)^2}

10 ( t + 2 ) 2 \frac{10}{\left(t+2\right)^2}
