Question

A particle moves along a circular path of radius 5 metre with constant speed 5 metre per second find the magnitude of average acceleration when it completes half revolution​

Answer 1

Explanation:

Given :--

vi= 5m/s

Vf = - 5m/s ( opposite direction )

R = 5m

aav = ?

Distance = R x pie

= 5 pie m

Time = Distance / vi

= 5pie/ 5m/s

= pie/second

Average acceleration = Vf - vi /t

= 5 - (-5) /pie

= 10 /pie m/s .
