A particle of mass m, initially at rest, moves on a horizontal line subject to a force F(t) = ae^(-bt). Show that the position and velocity of the particle as a function of time are: x = a/mb [t - 1/b (1 - e^(-bt))] and v = a/mb(1 - e^(-bt)).

A particle of mass $m$ is moving along the curve traced out by the vector function $\mathbf{r}=\mathbf{r}(t) .$ (a) Find the force acting on the particle at any time $t$. (b) Find the magnitude of the acceleration of the particle. $\mathbf{r}(t)=t \mathbf{i}+e^{t} \mathbf{j}$

The Dot Product
A particle of mass $m$ initially at rest, is acted upon by a variable force $F$ for a brief interval of time $T$. It begins to move with velocity $u$ after the force stops acting. $F$ is as a function of time shown in the graph. The velocity o $[$ the particle is: (a) $u-\frac{\pi F_{e}^{2}}{2 m}$ (b) $u-\frac{\pi T^{2}}{8 m}$ (c) $u-\frac{\pi F_{n} T}{4 m}$ (d) $u-\frac{F_{n} T}{2 m}$
