The figure shows the velocity time graph of the particle which moves along a straight line starting with velocity at `5 m//sec` and coming to rest at `t=30 s`. Then :-

Options

A. Distance travelled by the particle is `212.5 m`
B. distance covered by the particle when moves with constant velocity is `100 m`
C. Velocity of the particle at `t=25s` is `5 m//sec`
D. Velocity of the particle at `t=9s` is `8 m//sec`

Answer

A, C, D

Explanation

Area of the curve gives distance.
