Physics - Circular Motion Question with Solution | TestHub

The total acceleration of a particle moving in a circle of radius 4 m at a given instant is $a=$$20\mathrm{m}/{\mathrm{s}}^2$, directed at 37° from the radial line towards the velocity ( $\sin 37^{\circ }=0.6,\cos 37^{\circ }=0.8$). At this instant, find: (a) the radial acceleration, (b) the speed of the particle and (c) its tangential acceleration.
