Acceleration at any time t is the slope of v-t graph at that point t.

acceleration = slope of graph = tan Ф

= tan 30 deg = 1/√3 units

and tan 60 = √3 units

ratio = 1/√3 / (√3) = 1/3

acceleration = slope of graph = tan Ф

= tan 30 deg = 1/√3 units

and tan 60 = √3 units

ratio = 1/√3 / (√3) = 1/3
