Vedclass · Answer

$a_{t}=r \alpha=$ const. $\Rightarrow \alpha=$ const.

${\omega _i} = 0$          $	heta=2 \pi$

$\omega_{f}=\frac{V}{r}=\frac{80}{(20 / \pi)}=4 \pi$

$\alpha=\frac{\omega_{f}^{2}-\omega_{i}^{2}}{2 	heta}=2 \pi \operatorname{rad} / \sec ^{2}$

$\mathrm{a}_{\mathrm{t}}=\frac{20}{\pi} 	imes 2 \pi=40 \mathrm{\,m} / \mathrm{s}^{2}$

A particle moves along a circle of radius $\left( {\frac{{20}}{\pi }} \right)\,m$ with constant tangential acceleration. If the velocity of the particle is $80 \,m/s$ at the end of the second revolution after motion has begin, the tangential acceleration is
