A particle A is moving in xy plane with ...

A particle `A` is moving in `xy` plane with the constant speed of `2pi m//s` along the path `x^(2)+y^(2)+120y=0`. At time `t=0`. When `A` is at the origin, another particle `B` starts moving from origin with constant acceleration is such a way that at time `t=5s` velocities of both the particles are found to be equal. If sense of motion of `A` is clockwise, calculate the average speed of `B` over first five second.

The correct Answer is:
(a)`pi/5(-0.26hati)m//s^(2)`,(b)`(30hati-7.8hatj)m,pi(1.74hati-hatj)m//s`
