BEGINNER'S BOX-3
1.
A particle moves on circular path
vero
article moves on circular path of radius 5 m with constant speed 5 m/s. Find the magnitude of its
acceleration when it completes half revolution.
​

Answer 1

Answer:

10/pi

Explanation:

t=s/v=pi*r/5=pi(r=5 given)

so acceleration=change in velocity/time taken=-5-(5)/pi=-10/pi m/s2.
