The velocity time graph of a body moving along a straight line is shown in figure. The ratio of the average velocities during the time `t_1` and `t_2` is.

Options

A. `1 : 1`
B. `2 : 1`
C. `3 : 1`
D. `1 : 3`

Answer

A

Explanation

`v_(av^1)/(v_(av^2)) =(s_1)/(t_1)(t_2)/(s_2)`
=`((1)/(2) v_0 t_1)/(t_1) (t_2)/(((1)/(2) v_0 t_2)) = 1`.
