Question

A particle is constrained to move along a circular track of radius $R$. It is subjected to a resistive force such that it undergoes continuous deceleration. Measurements reveal that at every instant during its motion, the magnitude of its tangential acceleration is exactly equal to its centripetal acceleration. The particle was projected with an initial speed $v_0$ at time $t=0$.
