Question

A particle starts moving along a circle of radius 4 metre with constant tangential acceleration of 3 metre per second square the total acceleration of the particle at t is equal to 2 second makes an angle theta with the tangential acceleration where theta is equal to​

Answer 1

v=at

v=6m/s

v²/r=ac= 6*6/2=18m/s2

tanθ= 6

θ=$tan^{-1}$6
