A particle is moving in such a way that its velocity versus time graph is a parabola `(t=kv^(2),k` is constant) as shown in the figure. Choose the correct option(s)

Options

A. acceleration of the particle is `sqrt(3)m//s^(2)` throughout the journey
B. average acceleration of particle is `1m//s^(2)` for the interval of first 5 sec
C. average acceleration of particle is less than `sqrt(3)m//s^(2)` for the interval of first 5 sec
D. average acceleration of particle is less than `1m//s^(2)` for the interval of 5 sec to 10 sec

Answer

C, D

Explanation

Avg. acceleration `=("change in velocity")/("Time interval")`
