At the position shown, the particle traveling on a circular path has a speed $v = 8$ m/s, which is increasing at a rate of $3$ m/s$^2$. Also, $r = 2$ m, and $\theta = 90^\circ$. the particle reaches point A after half a turn. Determine, a) $\dot{r}$ and $\dot{\theta}$ (10 points) and b) $\ddot{r}$ and $\ddot{\theta}$ (10 points) of the particle at point A.

A particle travels around a circular path having a radius of $50 \mathrm{m}$. If it is initially traveling with a speed of $10 \mathrm{m} / \mathrm{s}$ and its speed then increases at a rate of $\dot{v}=(0.05 v) \mathrm{m} / \mathrm{s}^{2},$ determine the magnitude of the particle's acceleration four seconds later.
A particle travels around a circular path with a radius of 50 m. If it is initially traveling with a speed of 10 m/s and its speed then increases at a rate of v = (0.05v) m/s^2, determine the magnitude of the particle's acceleration four seconds later.

A particle is moving on a circular path of $10 \mathrm{~m}$ radius. At any instant of time, its speed is $5 \mathrm{~m} \mathrm{~s}^{-1}$ and the speed is increasing at a rate of $2 \mathrm{~m} \mathrm{~s}^{-2}$. The magnitude of net acceleration at this instant is (a) $5 \mathrm{~m} \mathrm{~s}^{-2}$ (b) $2 \mathrm{~m} \mathrm{~s}^{-2}$ (c) $3.2 \mathrm{~m} \mathrm{~s}^{-2}$ (d) $4.3 \mathrm{~m} \mathrm{~s}^{-2}$
