Question

please answer this question of kinematics.​

Answer 1

Answer:

As we all know that change in velocity = Vfinal - Vinitial

As the motion is circular Initial velocity = -v

Then change in velocity = 2v

Acceleration = 2v/t

= 2v^2/(pi*r)

= (2 x 100 xpi*pi)/(pi*1000)

= 22/35 m/s^2

A = change in velocity/time

22/35 = change in velocity
