An object with mass $m$ moves along the $x$ -axis. Its position at any time is given by $x(t)=p t^{3}+q t^{2}$ where $p$ and $q$ are constants. Find the net force on this object for any time $t$
An object of mass m is moving along the x-axis such that its position x is proportional to t^(1/2), where t is time. What is the magnitude of its acceleration?
For $t<0,$ an object of mass $m$ experiences no force and moves in the positive $x$ direction with a constant speed $v_{i}$ . Beginning at $t=0,$ when the object passes position $x=0$ , it experiences a net resistive force proportional to the square of its speed: $\overrightarrow{\mathbf{F}}_{\text { net }}= m k v^{2} \hat{\mathbf{i}},$ where $k$ is a constant. The speed of the object after $t=0$ is given by $v=v_{i} /\left(1+k v_{i} t\right)$ (a) Find the position $x$ of the object as a function of time. (b) Find the object's velocity as a function of position.
