The displacement of a body is proportional to t3, where t is What is tinc nature of acceleration -time graph of the body?

Explanation

As `aalphat^(2)implies" "s=kt^(3)`
Velocity, `V=(ds)/(dt)=3kt^(2)`
Acceleration, `a=(dv)/(dt)=6kt`
i.e., `apropt`
`implies` motion is uniform, acceleration motion, a-t graph is straight-line.
